The graph is a parabola with a vertex at -4
First, group them in 2's (2 numbers per group)
and see which ones have the factors of each other
you want to group 12x^3 with 3x because 3 is a factor of 12
then you want to group -20x^2 and -5 together becuase 5 is a factor of 20 so
(12x^3+3x)+(-20x^2-5)
undistribute
(3x)(4x^2+1)+(-5)(4x^2+1)
revese distribute (ab+ac=a(b+c))
(3x-5)(4x^2+1)
Answer:
x= 0, y=2
