Answer:
3 (x + 5) (x - 4)
Step-by-step explanation:
Factor the following:
3 x^2 + 3 x - 60
Factor 3 out of 3 x^2 + 3 x - 60:
3 (x^2 + x - 20)
The factors of -20 that sum to are 5 and -4. So, x^2 + x - 20 = (x + 5) (x - 4):
Answer: 3 (x + 5) (x - 4)
Find the GCF (Greatest Common Factor)
GCF = 3
Factor out the GCF (Write the GCF first. Then, in parentheses, divide each term by the GCF.)
3(3x^2/3 + 3x/3 - 60/3)
Simplify each term in parenthesis
3(x^2 + x - 20
Factor x^2 + x - 20
3(x - 4)(x + 5)
