i need help i don't know how to do the next step.
factor by grouping
x^33x^2+4x12
so what i have so far is this
=(x^33x^2)+(4x12)
=x(x^23x)+4(x3)
from here i don't know...
and then this one is driving me insane this next one...
Rewrite the middle term as the sum of two terms and then factor by grouping.
x^214x+45
i'd figure out problem #1
these are the steps I did:
factor by grouping
x^33x^2+4x12
so what i have so far is this
=(x^33x^2)+(4x12)
=x^2(x3)+4(x3)
= (x3)(x^2+4)
I AM STILL HAVING TROUBLE WITH PROBLEM NUMBER 2
to your second question
wouldnt it be
(x5)(x9)
You have to find 2 numbers to multiply to bed 45 BUT add to be negative 14.
