Answer:

Now we can solve a Quadratic Equation in 5 steps:

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.

We now have something that looks like (x + p)2 = q, which can be solved rather easily:

Step 4 Take the square root on both sides of the equation.

Step 5 Subtract the number that remains on the left side of the equation to find x.

Answer:

Put the x-squared and the x terms on one side and the constant on the other side.

Divide both sides by the coefficient of x-squared (unless, of course, it's 1).

Take half of the coefficient of x, square it, then add that to both sides.

Factor the left side.
