Question

Factor completely

bibby · Answer

we can start by factoring out an x. That leaves us with $\large x(x^2+2x-15)$

anonymous · Answer

bibby · Answer

factor the $\large (x^2+2x-15)$ so that we have 3 terms

anonymous · Answer

i dont know how to do that thats the problem can you explain it to me

bibby · Answer

Not sure what the best way to explain it is, you'd be better off on youtube.

What you want to do is find a combination of 2 numbers that are both factors of 15 and add up to 2.

Use the fact that {1,3,5,15} are the factors of 15
