There exist constants a, h, and k such that

3x^2 + 12x + 4 - 2x^2 + 11x - 7 = a(x - h)^2 + k

for all real numbers Enter the ordered triple (a,h,k).

3x^2 + 12x + 4 - 2x^2 + 11x - 7      simplify

x^2 + 23x -3                                  complete the square for 'x'

(x + 11.5)- 135.25      You can finish !    (hint: a =1)
