by completing the square .sh ) y=3x^2-12x+4

## Step 1: Rewrite the equation### Move the constant term to the right side of the equation. ## Step 2: Factor out the coefficient of the term### Factor out 3 from the left side. ## Step 3: Complete the square### Divide the coefficient of the term by 2 and square it: . Add this inside the parenthesis, and add 3 times this value (since we factored out a 3) to the right side to maintain balance. ## Step 4: Rewrite as a perfect square### Rewrite the left side as a perfect square. ## Step 5: Solve for x### Divide both sides by 3, then take the square root of both sides.
