Before you read this topic, you are advised to read:
What are Polynomials ?
What are degrees of Polynomial ?
What are the terms of Algebraic Equation ?
When the terms of a polynomial p(x) is written in descending order of their degrees, then we get the standard form of quadratic equation.
Example:2x2 + 5x + 200 = 0
In the above example you can see that 2x2 having degree of polynomial as 2 is written first and then 5x having degree as 1 and then 200. This way of writing the terms is called as standard form of quadratic equation.
Lets understand this further with the help of following examples:
Example 1: Write the following equation in standard form:
- 4x + 10x2 + 36 = 0
Solution: Write in descending order of their degrees and we get:
10x2 - 4x + 36 = 0
Example 2: Write the following equation in standard form:
- 4 - 7x + 36x2 = 0
Solution: Write in descending order of their degrees and we get:
36x2 - 7x - 4 = 0
Example 3: Write the following equation in standard form:
5x2 - 10 + 6x = 0
Solution: Write in descending order of their degrees and we get:
5x2 + 6x - 10 = 0
