Answer 1

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)

Answer 2

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)
