Question

factor: 6x^2-20x-16

Answer 1

I first used the quadratic formula to get a general idea of what the solution should be. Do you know how to do that?

Answer 2

That brought me to (x-4)(x+2/3) which obviously is not the factorization.
But I noticed that I just needed to multiply the first binomial by 2 and the second by 3 to get (2x-8)(3x+2) which works.

Answer 3

yes I know the quad formula. I didn't even think to work backwards. Thank you!

Answer 4

Glad to help. :)
