Factor by grouping x^2+10x+25

OpenStudy (anonymous):

(x+5) (x+5)

OpenStudy (luigi0210):

Stop giving away answers..

OpenStudy (anonymous):

can you show me step by step how you got that answer by using factoring by grouping so i can understand it

OpenStudy (anonymous):

Ye i know what the answer is just want to know how to get it.

OpenStudy (anonymous):

find constants that add up to 10, and multiply to 25. (factors of 25)

OpenStudy (anonymous):

Oh. I don't know how to factor by grouping..

OpenStudy (anonymous):

ohh k how do you do the special product of the same function?

OpenStudy (luigi0210):

By grouping you say? That's interesting.

OpenStudy (anonymous):

yes by grouping

OpenStudy (luigi0210):

But I see what you mean. I can show you if you want?

OpenStudy (anonymous):

yeah kind of the wrong technique but it can be done

OpenStudy (anonymous):

yes please

OpenStudy (luigi0210):

First what you have to do is break that 10x apart to 5x+5x

OpenStudy (anonymous):

no, ehuman meant that my Technic was wrong, b/c what if the coefficient(s) are more or less than 1?

OpenStudy (anonymous):

okay

OpenStudy (anonymous):

so its x^2+5x+5x+25?

OpenStudy (anonymous):

basically. you are correct!

OpenStudy (anonymous):

then what

OpenStudy (luigi0210):

Now just factor by grouping :)

OpenStudy (anonymous):

how?
