Step 1 Divide all terms by a (the coefficient of x2 ). Step 2 Move the number term ( c/a) to the right side of the equation. Step 3 Complete the square on the left side of the equation and balance this by adding the same value to the right side of the equation.
May 15, 2024 · Completing the square is a helpful technique that allows you to rearrange a quadratic equation into a neat form that makes it easier to visualize or even solve. It’s used to determine the vertex of a parabola and to find the roots of a quadratic equation.
Your completing the square method is exactly on point with the first half. Just remember when you find (b/2)², you must add that result in the parenthesis, and subtract it out and multiply it by the 4 by the number outside.
To complete the square, first, you want to get the constant (c) on one side of the equation, and the variable(s) on the other side. To do this, you will subtract 8 from both sides to get 3x^2-6x=15. Next, you want to get rid of the coefficient before x^2 (a) because it won´t always be a perfect square.
