Question

Using complete sentences, explain how to completely factor 3x2 − 3x − 60.

Answer 1

first you would factor out the 3

Answer 2

giving you\[3(x^2 -x-20)\]

Answer 3

then you find two numbers that multiply to make -20, but also when added together give you -1

Answer 4

and then in this case the numbers would be 4 and -5

Answer 5

which would be (x+4)(x-5)

Answer 6

and since you still have that 3 you factored out, you bring it back in and it would be 3(x+4)(x-5)

Answer 7
