How To Solve Quadratic Equations In Seconds Quick Easy Trickо A quadratic equation is a polynomial equation in a single variable where the highest exponent of the variable is 2. there are three main ways to solve quadratic equations: 1) to factor the quadratic equation if you can do so, 2) to use the quadratic formula, or 3) to complete the square. if you want to know how to master these three methods. The complete solution of the equation would go as follows: x 2 − 3 x − 10 = 0 ( x 2) ( x − 5) = 0 factor. ↙ ↘ x 2 = 0 x − 5 = 0 x = − 2 x = 5. now it's your turn to solve a few equations on your own. keep in mind that different equations call for different factorization methods. solve x 2 5 x = 0 . step 1. Example 4: the quad equation 2x 2 9x 7 = 0 has roots α, β. find the quadratic equation having the roots 1 α, and 1 β. solution: method 1: the quadratic equation having roots that are reciprocal to the roots of the equation ax 2 bx c = 0, is cx 2 bx a = 0. the given quadratic equation is 2x 2 9x 7 = 0. I did not find this trick useful specifically for this equation for the following reason: observation. the implementation of this trick is based on the following observation: $$150 2=152, ~ 150\times 2=300.$$ isn't it? but, this trick already works in the original equation: $$\begin{align}3x^2 152x 100=0\end{align}$$ $$\iff 3x^2 150x 2x 100=0.$$.
