To complete the square for a standard equation you ll need to transform the equation to vertex form Start by factoring out the coefficient of the squared term from the first two terms then halve the second term and square it Next add and subtract this term from the equation 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.

How To Complete The Square Formula1) Divide the entire equation by 5: x^2 - 2x = 23/5 2) Complete the square: -2/2 = -1. (-1)^2 = +1. Add +1 to both sides: x^2 - 2x + 1 = 23/5 + 1 3) Rewrite the left side as a binomial squared, and add the fractions on the right: (x-1)^2 = 28/5 4) Take square root of both sides: sqrt(x-1)^2 = +/- sqrt(28/5) 5) Simplify both radicals: x-1 . 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
