In mathematics, we often deal with equations which are defined as the relations between variables and constants connected with one another by the use of algebraic operators.
The equation may be of different types on the basis of highest power i.e. the degree of the equation:
1) Linear Equations: The degree equal to 1.
For example: x + 1 = 3
2) Quadratic Equations:The degree equal to 2.
For example : x2 + 3x - 4
3) Cubic Equations: The degree equal to 3.
For example : 5x3 - 3x2 + x - 7
4) Biquadratic Equations: The degree equal to 4.
