Question

Factor. Check by multiplying factors

8x^3+2x^2+12x+3

Answer 1

Set the equation to = 0.

8x^3 + 2x^2 + 12x + 3 = 0

Answer 2

what? o_o

Answer 3

Hero is about to explain. :D

Answer 4

Factor by grouping:

Notice that
8x^3 + 2x^2 = 2x^2(4x + 1)
12x + 3 = 3(4x + 1)

That leaves something common to both factorizations.

Answer 5

4x+1

Answer 6

Can you figure out the complete factorization from here?

Answer 7

2x^2(4x+1)= 8x^2+2x^2
3(4x+1)= 12x+3

Answer 8

Start from this form:
8x^3 + 2x^2 + 12x + 3

Answer 9

Your end result needs to be in the form
(ax + b)(cx^2 + d)
