![]() ![]() 1 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. It might sound complicated, but converting to standard form is pretty easy. A quadratic equation is a polynomial equation in a single variable where the highest exponent of the variable is 2. Standard form means the equation equals “0” and is ready to solve. Enter 1, 1 and 6 And you should get the answers 2 and 3 R 1 cannot be negative, so R 1 3 Ohms is the answer.
