This note gives geometrical/graphical methods of finding solutions of the quadratic equation ax 2 + bx + c = 0, a p 0, with non-real roots. Three different cases which give rise to non-real roots of the quadratic equation have been discussed. In case I a geometrical construction and ...
A general cubic equation ax3 + bx2 + cx + d = 0 where a, b, c, d ∈R, a ≠ 0 has three roots with two possibilities—either all three roots are real or one root is real and the remaining two roots are imaginary. Dealing with the second possibility this paper attempts to give ...

There are two ways to solve a cubic equation without using a quadratic formula: factoring and graphing. These are the steps to use to find the roots of a cubic equation by factoring Use the rational roots test to find the first solution. Factor that root out of the equation using synth...
The roots of the equation are those values of the variable, x, where f(x) equals zero. The number of roots of the equation depends on the order of f(x). If f(x) is a second-order, quadratic equation, it has two roots that can be determined analytically with ease. Third-order cu...
