for what real values of c is x^2 - 8x + c the square of a binomial?

 

for what real values of s is x^2 + sx + 144 the square of a binomial?

 

for what real values of c is 4x^2 + 14x + c the square of a binomial?

 

thanks!! :))

1)

 

(8/2)^2=16, so, c=16

2)

 

(s/2)^2=144

 

So, s=24, s=-24

He was close, but don't forget that -24 works too, since (-12)^2=144 too!

I saw you asking for hw questions. It is all in your history. Stop being such a hypocrite. Also, aren't we supposed to ask for help when we have a question with hw? This place is for questions, and why don't you stop criticising and actually try to help, like Cal is doing!

i never asked for the answers. calthegreat just gave me them, which is also helpful since they gave an explanation. also, you spelled that wrong. it's technically capiche. there are multiple spellings, but yours is way off :)

No, I'm assuming it might have come from Introduction to Pre-Algebra or whatever it's called, given the depth of AoPS courses.

I do not believe you mattewmacdell,

 

If you wanted to learn you would ask just one of these questions and then you would attempt the others on your own with your increased knowledge.

STOP BEING A HYPOCRITE. YOU POSTED HOMEWORK TOO YOU KNOW. IN FACT, IT IS FROM THE SAME WEBSITE.

Are you familiar with the fact that \((a+b)^2=a^2+2ab+b^2\)? A strong understanding of this will help you find the answer easily.
