For example, the equation . 5x 3 + x 2 – 45x – 9 = 0 WebOct 13, 2024 · Alternative Method of Solving Quadratic Equations. If you find r and s with sum − B and product C, then x 2 + B x + C = ( x − r) ( x − s), and they are all the roots. Two numbers sum to − B when they are − B 2 ± u. Their product is C when B 2 4 − u 2 = C. Square root always gives valid u. Thus − B 2 ± u work as r and s, and are ...
