QuestionComplete the square for h(x)=5x2+20x−60h(x)=5 x^{2}+20 x-60 x=−2h(x)=5x2+2h(−2)=−80(−2,−80)\begin{array}{l} x=-2 \\ h(x)=5 x^{2}+2 \\ h(-2)=-80 \\ (-2,-80) \end{array}

Studdy Solution
The completed square form of h(x)h(x) is h(x)=5(x+2)2−80h(x) = 5(x+2)^2 - 80.
This tells us the vertex of the parabola is at (−2,−80)(-2, -80)!
