WebYou can put this solution on YOUR website! x^2+8x+15=0. This quadratic equation is written in standard form: We need to factor the quadratic equation. Our a=1, b=8, and c=15. Because a=1, we can start out factoring like this: (x____) (x____)=0. We replace the blank with 2 integers that multiply to give you c, but add together to give you b. WebExample 1: Given x 2 + 5x + 6 = 0. ( x + 3) ( x + 2) = 0 (factoring the polynomial) ( x + 3) = 0 OR ( x + 2) = 0. Thus x = −3, Or x = −2. The example above shows that it is indeed easy to solve quadratics by factoring method. However, the method only works for the most basic equations. Ideally the method will only work on quadratics with ...
