The function p(x) = –8x2 – 64x can be written in vertex form p(x) = a(x – h)2 + k, where a = , h = , and k = .
Answers: 1
![\begin{array}{l}Convert\ p(x)=-8x^2-64x\ to\ \text{vertex form}\\\\p(x)=-8\left[x^2+8\right]\\\\p(x)=-8\left[x^2+2\cdot x\cdot4+4^2-4^2\right]\ \longrightarrow h=\frac{-b}{2a}=\frac{-16}{2\left(2\right)}=-4\\\\p(x)=-8\left[(x+4)^2-16\right]\\\\p(x)=-8(x+4)^2+128\\\\So\ we\ have\ got,\ a=-8,\ h=-4,\ k=128\end{array}](/tpl/images/2599/1518/76faa.png)
