By definition, an equation can have different forms and there are different types of equations. Some of them are shown below:
1. Linear equation: It has one variable whose exponent is 1. It has one solution. Its form can be:
[tex]ax+b=0[/tex]2. Quadratic equation: It is an equation whose variable has exponent 2. These equation can be expressed as
[tex]ax^2+bx+c=0[/tex]
