Question

Step by step please :(
Convert the equation to Standard Form.

y=2(x+1)^(2)-4

Answer 1

y = 2x^2 + 4x - 2

Explanation:

y=2(x+1)^(2)-4 is in vertex form. We want the same equation in standard form, which looks like y = ax^2 + bx + c.

Perform the indicated multiplication (squaring of x + 1):

y = 2(x^2 + 2x + 1) - 4, or

y = 2x^2 + 4x + 2 - 4, or

y = 2x^2 + 4x - 2 This is in the standard form of a quadatic.
