Convert it into standard form

Option 1. y = 2 - 4x + 6

Step-by-step explanation:

To convert the equation into standard form, the first thing we have to do is FOIL the (x - 1)^2.

(x - 1)(x - 1) = - 2x + 1

Now the function looks like: y = 2( - 2x + 1) + 4

Now we have to distribute the 2 to everything inside the parentheses

2 * = 2     2 * -2x = -4x     2 * 1 = 2

Now the function looks like:  2 - 4x + 2 + 4

Combine like terms: 2 - 4x + 6

The function in standard form is 2x^2 - 4x + 6, or option 1
