Question

How can i completly factor this equation? 3x^2 - 3x - 60

Answer 1

first take out the GCF for the trinomial...3(x^2 - x -20). it should be easier to factor now...

Answer 2

how do I factor it completly...

Answer 3

3(x+4)(x-5)

Answer 4

can u show me step by step?

Answer 5

sure....

Answer 6

thats never an easy task is it

Answer 7

assume it factors:

(x+a)(x+b) = x^2 -x -20

expand the left side

x^2+(a+b)x +ab = x^2 -x -20

and compare coeeficients is prolly the simplest route
