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

3(3d³ - 4a²)

Step-by-step explanation:

We have to factorize the algebraic expression as 9d³ - 12a².

Now, we have to take common the equal term from both the part of the expression for the purpose of factorization.

But, the only common term among the two terms from the expression is 3.

Therefore, the required factorization is 3(3d³ - 4a²). (Answer)

i think the answer is b
