**Quadratic Equation Practice Questions and Tutorial**

For every quadratic equation, there can be one or more than one solution. These are called the roots of the quadratic equation. For a quadratic equation ax 2 +bx+c = 0, the sum of its roots = –b/a and the product of its roots = c/a. A quadratic equation may be expressed as a product of two binomials. For example, consider the following equation
