# Solving Quadratic Equations

Quadratic equations are where the degree of the polynomial is $2$. The standard form of the quadratic equation is $ax^2 + bx + c$ = $0$ where $a \neq 0$. Solving the quadratic equation we can get $1, 2$ or $0$ real solutions. There are many methods of solving quadratic equations like

• Solving by Graphing

• Solving by factorization

• Solve using quadratic formula

• Solving by square root method

• Solve by completing the square.

This lesson we are going to concentrate on solving the quadratic equation by factorization and by completing the square.
