Question

For the following quadratic, find the vertex, the vertical intercept, and the horizontal intercepts
y(x) = 2x^2+10x+12

Answer 1

I know that I can factor out the equation to get my vertex, but I can only factor as far as a 2 so I have 2(x^2+5x+6)

Answer 2

How do I factor that out more?

Answer 3

1. f(x) = x^2 - 6x + 8
y = f(x) so write it:
y = x^2 - 6x + 8

Answer 4

Oh, it should be 2x^2 so that I can factor out a 2

Answer 5

2x^2+10x+12 is the equation
