Question

factor using the gcf. do not put any spaces in your answer.
3x^3+9x-4x^2-12
note: use the ^ symbol to represent exponents. for example, x^2 means \x squared\

Explanation:

Step1: Group terms by pairs

$(3x^3 + 9x) + (-4x^2 - 12)$

Step2: Factor GCF from each pair

$3x(x^2 + 3) - 4(x^2 + 3)$

Step3: Factor out common binomial

$(x^2 + 3)(3x - 4)$

Answer:

(x^2+3)(3x-4)
