Write y=2x^2-12x+16 in vertex form

leva [86]

Answer:

y = 2 $(x - 3)^{2}$ - 1

Step-by-step explanation:

y = 2 $x^{2}$ - 12x + 16

y = 2( $x^{2}$ - 6x + 8) ( Factor out 2 )

y + 9= 2( $x^{2}$ - 6x + 9) + 8 ( Complete the square $(\frac{-b}{2} )^{2}$ ) Add 9 both sides

y + 9 = 2 $(x - 3)^{2}$ + 8 (Subtract 9 each side)

y = 2 $(x - 3) ^{2}$ - 1 ( simplify )
