@One098 Can you help me?

OpenStudy (one098):

Sure, what's the question?

OpenStudy (anonymous):

give me one second

OpenStudy (one098):

Alright, take your time.

OpenStudy (anonymous):

they ask me to factor out x^2+91

OpenStudy (one098):

\[x^{2}+91\] Okay so first, what multiplied by 2 will give you: \[x^{2}\]

OpenStudy (anonymous):

x times x ?

OpenStudy (anonymous):

Yes, that's correct.

OpenStudy (anonymous):

Now what times what equals 91?

OpenStudy (one098):

Okay, good. Now what two numbers give you 91?

OpenStudy (anonymous):

So far we have: \((x +~?)(x +~?)\)

OpenStudy (anonymous):

Find the factors of 91, and pick 2.

OpenStudy (anonymous):

Here's one: What's 91 / 7?

OpenStudy (anonymous):

Can you divide that? @itsjustyou
