# Quadratic equation grade 9

**Quadratic equation** means that it will definitely have the maximum power of the variable as ‘2’ which means we will always see ax 2 term in a **quadratic equation**. Or we can say that b can be 0, c can be 0 but a will never be 0. While solving **quadratic equation**, you will always get 2.

Name: _____Math Worksheets Date: _____ So Much More Online! Please visit: EffortlessMath.com Solving a **Quadratic Equation** Solve each **equation** by factoring or using the **quadratic** formula. So, the standard form of a **quadratic equation** is as: ax 2 + bx + c = 0, (a ≠0) Where, a, b and c are called as the coefficients of x 2, x and x 0 respectively. c is also called as the Constant Term. In this **equation**, x is unknown quantity and therefore it is called as the Variable. A general **quadratic equation** consists of three terms ax 2, bx. Compiled by the editors of TeacherVision ®. Patterns, ratios, equality, algebraic functions, and variables are some of the concepts covered in this printable book for elementary students.

The solution (s) to a **quadratic equation** can be calculated using the **Quadratic** Formula: The "±" means we need to do a plus AND a minus, so there are normally TWO solutions ! The blue part ( b2 - 4ac) is called the "discriminant", because it can "discriminate" between the possible types of answer: when it is negative we get complex solutions. **Quadratic equation** quiz with answer key online. There are several methods for solving **quadratic equations** one key method being the use of the **quadratic** formula. Whatever method you use, the outcome is two values of 'x'. If you substitute any of both values of 'x' in the **equation**, the outcome will always be the same. In this method, you will learn how to find the roots of **quadratic equations** by the method of completing the squares. The steps involved in solving are: For the **equation**; a x 2 + b x + c = 0. First, divide all terms of the **equation**.
