Which equation is y = 2x2 – 8x + 9 rewritten in vertex form?

a. y = 2(x – 2)2 + 9
b. y = 2(x – 2)2 + 5
c. y = 2(x – 2)2 + 1
d. y = 2(x – 2)2 + 17

i want to die

what the hell man, i just want the points lol

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
