Question

Convert the following quadratic to vertex form:

2(x-4) (x - 2)
y =
=
Oy=2x²-12x+16
Oy=2(x-3)²-2
Oy=2(x-3)²-1
Oy=2(x²-6x+8)

Answer 1

`y=2(x-3)^2-2`

Explanation:

`y=2(x-4)(x-2)\\y=2(x^2-6x+8)\\y+2(1)=2(x^2-6x+8+1)\\y+2=2(x^2-6x+9)\\y+2=2(x-3)^2\\y=2(x-3)^2-2`

Answer 2

Answer: The given expression is already in the vertex form:

y = 2(x-3)² - 1

It is the standard form of a parabolic equation with the vertex at (3, -1) and opens upwards.
