Question

I don’t know how to type exponents our on here, so whenever I put a ^ before a number, it’s an exponent :) ex: ^3 (the exponents 3)

the question:
Factor.
9d^3 - 12a^2

Answer 1

Answer: 3(3d^3-4a^2\)

Explanation:

Rewrite -12 as 4 x 3 and rewrite 9 as 3 x 3 which should give you something like this = 3 x 3d^3+4 x 3a^2 and then factor out the common term which is 3 and your answer should be this =3(3d^3-4a^2)

Answer 2

So you can’t factor out the variables since one is d and the other is a. If they were the same letter you could factor them out as well
The only number that goes into both 9 and 12 is three
So divide by three essentially and take it out and place is next to the rest of the equation that is now in parenthesis
3(3d^3 - 4a^2)
