★ Lightweight.

NOTE : Quadratic equations are of the form ax2+bx+c=0 where a, b and c are real numbers and "a" should not be equal to zero. Quadratic equations have two solutions. It is possible that one solution may repeat. You can calculate quadratic equations by Completing the square and by Quadratic Formula.

Solving by Competing the Square

• Keep all terms containing x on one side. Move the constant to the right.

• Get ready to create a perfect square on the left. Balance the equation.

• Take half of the x-term coefficient and square it. Add this value to both sides.

• Simplify and write the perfect square on the left.

• Take the square root of both sides. Be sure to allow for both plus and minus.

• Solve for x.

Solving by Quadratic Formula

The solutions of some quadratic equations are not rational, and cannot be factored. For such equations, the most common method of solution is the quadratic formula. The quadratic formula can be used to solve ANY quadratic equation.
