If you've got a quadratic equation on the form of ax^2 + c = 0 Then you can solve the equation by using the square root of x = square_root(-c/a) or x = -square_root(-c/a)

An algebraic expression where both the numerator and the denominator are polynomials e.g.(x+3) / x is called a rational expression. Since the denominator can't be zero there are values of x which are excluded from the rational...

An equation that contains at least one rational expression is called a rational equation. You solve a rational equation as you solve any other equation.
