Write as a Function of x 4x^2-4x+2y=y

$4 x^{2} - 4 x + 2 y = y$

Step 1

Move all terms containing $y$ to the left side of the equation.

Subtract $y$ from both sides of the equation.

$4 x^{2} - 4 x + 2 y - y = 0$

Subtract $y$ from $2 y$ .

$4 x^{2} - 4 x + y = 0$

Step 2

Move all terms not containing $y$ to the right side of the equation.

Subtract $4 x^{2}$ from both sides of the equation.

$- 4 x + y = - 4 x^{2}$

Add $4 x$ to both sides of the equation.

$y = - 4 x^{2} + 4 x$

Step 3

To rewrite as a function of $x$ , write the equation so that $y$ is by itself on one side of the equal sign and an expression involving only $x$ is on the other side.

$f (x) = - 4 x^{2} + 4 x$

Write as a Function of x 4x^2-4x+2y=y
