# Root of an Equation

## Root of an Equation

• In the equation 0x = 0, all values of x are solutions or roots of the equation.
• The equation ax + b = o, where a ≠ 0, has only one root, that is x = – $$\frac{\textrm{b}}{\textrm{a}}$$.

### Examples

• The solution set of the equation 3x + 4 = 7 is {1}.
• The two roots of the equation x2 – 3x + 2 = 0 are x$$_{1}$$ = 2 and x$$_{2}$$ = 1.
