This should help you visualize the equation:

Here's a direct derivation:

Thank you. I'm having doubts about my answer but now I see where I am wrong

(2x+1)/(x^(2)-1)+(x)/(x^(2)-3x+2)=4

I'll try and make sense of your question first

\(\frac{(2x+1)}{(x^{2}-1)}+\frac{(x)}{(x^{2}-3x+2)}=4\qquad x\ne\pm1\\ \frac{(2x+1)}{(x-1)(x+1)}+\frac{(x)}{(x-2)(x-1)}=4 \qquad x\ne\pm1,\quad x\ne2\\ \frac{(2x+1)(x-2)}{(x-1)(x+1)(x-2)}+\frac{(x)(x+1)}{(x-2)(x-1)(x+1)}=4\\ (2x+1)(x-2)+(x)(x+1)=4(x-1)(x+1)(x-2)\\ 2x^2-4x+x-2+x^2+x=4(x-1)(x+1)(x-2)\\ 3x^2-3x+x-2=(x-2)(4x^2-4)\\ 3x^2-2x-2=4x^3-4x-8x^2+8\\ 0=4x^3-4x+2x-8x^2-3x^2+8+2\\ 0=4x^3-11x^2-2x+10\\ \)

Here is the approximate answers

73,  89,  81,  95,  87

The highest value in the list is  95  .

The lowest value in the list is  73  .

range  =  highest value - lowest value

range  =  95 - 73

range  =  22

3x² + 7x - 6

Multiply the  3  and  -6  together to get  -18 .

What two numbers add to  7  and multiply to  -18  ? →  +9  and  -2

So...we can split the middle term like this...

=  3x² + 9x - 2x - 6            Now factor a  3x  out of the first two terms.

=  3x(x + 3) - 2x - 6            Now factor a  -2  out of the last two terms.

=  3x(x + 3) - 2(x + 3)         Now factor a  (x + 3)  out of both remaining terms.

=  (x + 3)(3x - 2)

Welcome to the web2.0calc forum. 

My fist piece of advise is to make sure you're really are asking the question that you need answered.

No one here, with the possible exception of GingerAle, is a mind reader.

You have not asked a question. 

3x-y=9

    +y     +y

3x=9+y

divide both sides by 3

3x/3=(9+y)/3

x     = 3+(y/3)

choose any number for y, put it in the equation and solve for x, this will create a line as this is a line equation.

x and y could be anything really......

Actually I just solved it. You have 4 postcards and 3 mail boxes. We need to treat each postcards as an entity of its own. 1 Postcard has 3 options, to either go to mailbox 1, mailbox 2, or the third mailbox. That is 3 options. Since there is 4 postcards. It is then, 3 options 4 times. Translate to 3 * 3 * 3 * 3, or simply: 3^4.

solve and graph the soltion on a number line: 6-5ma>161

\(6-5ma>161\\ -5ma>155\\ -ma>31\\ ma<31\\\)

ma is not just one pronumeral so it would not normally be graphed on a number line.

There are an infinite number of solutions for m and a

I don’t understand why someone put this letter here. What does it have to do with this posts?  

Also what are E. F. Gnomes?  

I don’t get any of this.

We are not here to do all your homework for you.

Don't be so lazy!

Thank you!!

Simplify the following:
(i sqrt(5) + 3)^2

(i sqrt(5) + 3)^2 = 9 + 3 i sqrt(5) + 3 i sqrt(5) - 5 = 4 + 6 i sqrt(5):
6 i sqrt(5) + 4

Factor 2 out of 4 + 6 i sqrt(5) giving 2 (3 i sqrt(5) + 2):
Answer: | 2(3i sqrt(5) + 2)

A MOTHER'S LETTER

Dear Son.
Just a few lines to let you know that I’m still alive.  I’m writing this slowly because I know that you can’t read fast.  You won’t know the house when you come home, we have moved.

About your father.  He’s got a lovely new job.  He has 500 men under him.  He cuts grass at the cemetery.  Your sister Mary had a baby this morning. I haven’t found out yet whether it’s a boy or a girl so I don’t know if you are an aunt or an uncle.

I went to the doctors on Thursday and your father came with me.  The doctor put a small tube in my mouth and told me not to talk for 10 minutes.  Your father offered to buy it from him.  Your uncle Patrick drowned last week in a vat of Irish whiskey at the Dublin brewery.  Some of his workmates tried to save him but he fought them off bravely.  They cremated him and it took three days to put the fire out.

It only rained twice this week, first for 3 days then for 4 days.  We had a letter from the undertaker.  He said if the last payment on your grandmother’s plot wasn’t paid in 7 days, up she comes 

                             Your loving mother.

P. S.  I was going to send you 5 pounds but I have already sealed the envelope.

2017^2017=?

Take the log of 2017 =3.3047058982127654361280880089594.......

Multiply the above log by the exponent(2,017):

3.3047058982127654361280880089594  x 2,017 =6,665.5917966951478846703535140712 This is the log of:

2,017^2,017 =10^0.5917966951478846703535140712 x 10^6,665

=3.906579755433...... x 10^6,665

Secant (pi/360) =1.0000380783857.......

if x > 1, then for what positive base b is logb(x) is always equal to 3/4 of log10^x?

Example:
Solve for b:

logb(10000) =3
(log(10000))/(log(b)) = 3 ="3/4 of Log 10^4 or10,000"

Take the reciprocal of both sides:
(log(b))/(log(10000)) = 1/3

Multiply both sides by log(10000):
log(b) = (log(10000))/3

(log(10000))/3 = log(10000^(1/3)) = log(10 10^(1/3)):
log(b) = log(10 10^(1/3))

Cancel logarithms by taking exp of both sides:
Answer: | b = 10 10^(1/3) =10,000^1/3 or "a"

Find the least common multiple or common denominator:
lcm(2, 3, 4, 5)
Find the prime factorization of each integer:
The prime factorization of 2 is:
2 = 2^1
The prime factorization of 3 is:
3 = 3^1
The prime factorization of 4 is:
4 = 2^2
The prime factorization of 5 is:
5 = 5^1
Find the largest power of each prime factor.
The largest power of 2 that appears in the prime factorizations is 2^2.
The largest power of 3 that appears in the prime factorizations is 3^1.
The largest power of 5 that appears in the prime factorizations is 5^1.
Therefore lcm(2, 3, 4, 5) = 2^2×3^1×5^1:
Answer: | lcm(2, 3, 4, 5) = 60

Maybe this will help
