which function is equivalent to q(x)=9x^2-24x+15

Answer 1

q(x) = 9x^2 -24x +15

q(x) = (3x-3)(3x-5)

q(x) = (3)(x-1)(3x-5)

also

q(x) = (9)(x^2 -8x/3 + 16/9) +15 - 9(16/9)

q(x) =9(x-4/3)^2 - 1 where (4/3, -1) is the vertex of the parabolic function and the minimum point of the upward opening parabola
