algebra 1 sem2
lesson 2.2 - using gcf to factor
< 9 of 9 1 2 3 4 5 6 7 8 9
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 group

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

Step3: Factor out common binomial

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

Answer:

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