Question

18 Write y = 2x*+8x+10 in vertex form.y = 2(x+8)* +10y = (x+2)+10y = 2(x + 2) + 2y = 4(x +4+2

Answer 1

Given data:

The given equation is y = 2x^2+8x+10 .

The givenn equation can be written in vertex form as,

`\begin{gathered} y=2x^2+8x+10 \\ =2(x^2+4x)+10 \\ =2(x^2+4x+4-4)+10 \\ =2(x+2)^2+2 \end{gathered}`

Thus, the given equation can be written as, 2(x+2)^2 +2, so third option is correct.
