Strategy <strong>to</strong> <strong>Solve</strong> <strong>Cubic</strong><br />
<strong>Equation</strong><br />
Unlike quadratic equation which may have no<br />
real solution; a cubic equation always has at<br />
least one real root. The prior strategy of solving<br />
a cubic equation is <strong>to</strong> reduce it <strong>to</strong> a quadratic<br />
equation, and then solve the quadratic by usual<br />
means, either by fac<strong>to</strong>rizing or using a formula.<br />

equations with the help of the general equation,<br />
ax 3 + bx 2 + cx+d= 0
