(2x + y) + (x + y)

(2x + x) + (y + y)

3x + 2y

Hello , 

10+10=20

You can easily solve this with the calculator : http://web2.0rechner.de/

A prime number (or a prime) is a natural number greater than 1 that has no positive divisors other than 1 and itself. A natural number greater than 1 that is not a prime number is called a composite number. For example, 5 is prime because 1 and 5 are its only positive integer factors, whereas 6 is composite because it has the divisors 2 and 3 in addition to 1 and 6.

A monomial is an expression in algebra that contains one term, like 3xy.Monomials include: numbers, whole numbers and variables that are multiplied together, and variables that are multiplied together.

(-2)^2 (1+1)+2 = 4 (2) + 2 = 10

Thanx Guest 1     .....    I learned from your answer how to do this mathematically.   I typically revert to graphical solutions when I do not know how to calculate an answer...here is the graph of the equation...... you can see the zeros are at -.2 +.2 and -1.5     so the dimensions are

(b+1.5)(b-.2)(b+.2)      which is the same as guest calculated (though simplified)

Well ....  image uploader is not funcioning presently....will post graph when it becomes available...

You could try reading the textbook String Theory, by Joseph Polchinski of the University of California, Santa Barbara, where the equation appears.  Good luck with that!

17^1234567 mod 18 = 17 the remainder. You cooked this one up didn't you??.

Factor the following:
50 b^3 + 75 b^2 - 2 b - 3

Factor terms by grouping. 50 b^3 + 75 b^2 - 2 b - 3 = (50 b^3 + 75 b^2) + (-3 - 2 b) = 25 b^2 (2 b + 3) - (2 b + 3):
25 b^2 (2 b + 3) - (2 b + 3)

Factor 2 b + 3 from 25 b^2 (2 b + 3) - (2 b + 3):
(2 b + 3) (25 b^2 - 1)

25 b^2 - 1 = (5 b)^2 - 1^2:
(5 b)^2 - 1^2 (2 b + 3)

Factor the difference of two squares. (5 b)^2 - 1^2 = (5 b - 1) (5 b + 1):
Answer: |(5 b - 1)* (5 b + 1)* (2 b + 3)

Hello Majid:

                   The best explanation of this great discovery is here:

https://www.youtube.com/watch?v=jcKRGpMiVTw&t=638s

This is called "Euler-Riemann zeta function". Its importance in physics is mainly in the "String Theory", but its treatment is highly advanced mathematics.

I have seen this before Majid.  I call it 'math magic'   :)

Maybe Alan can say something more helpful :)  

Do you want the proof or do you just want to know how it can be useful ?

(k-9)(k+9)

 y=7\sin\left(\dfrac{3\pi}{4} x-\dfrac{\pi}{4}\right)+6y=7sin(​4​​3π​​x−​4​​π​​)+6

What do you want me to do with this?  Do you want to grapoh it?

\( y=7\sin\left(\dfrac{3\pi}{4} x-\dfrac{\pi}{4}\right)+6\)

\( y=7\sin\left(\dfrac{3\pi}{4} x-\dfrac{\pi}{4}\right)+6\\ y=7\sin\left(\dfrac{3\pi}{4}\left[ x-\dfrac{1}{3}\right]\right)+6\\ \text{This is a Sine curve}\\ \text{the period is }2\pi \div \frac{3\pi}{4}=2\pi \times \frac{4}{3\pi}=\frac{8}{3}\\ \text{The phase shift is }\frac{1}{3} \text{ units to the right}\\ \text{The centre of the wave is y=6}\\ \text{And the amplitude is 7}\)

Here I have built the graph - bit by bit as described above :)

Sin(75) = sin (45 +30)

trig identity :  sin (x+y) = sinx cosy +cosxsiny

sin(45+30) = sin45cos30 + cos45sin30

                  = (sqrt2 /2)(sqrt3 /2) + (sqrt 2 /2 * 1/2)

                 = ( sqrt 6) /4  +  sqrt 2/4

                   1/4 (sqrt 6 + sqrt 2)

\({k}^{2} -17k+16=0 \)

delta b²-4ac = (-17)²-4*1*16 = 225

\({k}_{1}= \frac{17+15}{2} = 16\)

\({k}_{2}=\frac{17-15}{2} = 1\)

\({k}^{2} -17k+16= (k-16)(k-1) \)

yes
