The key is incorporating the factor theorem. We will first solve some quadratic equations by using the Zero Product Property. To solve a quadratic equation by factoring Put all terms on one side of the equal sign leaving zero on the other side.
Then use process of elimination to plug in the factors of 4 to find a combination that.
This is a biquadratic equation which gives the roots x2 4 and x2 1. How Does this Work. See examples of using the formula to solve a variety of equations. X 2 x2 ax b 0 x 2x2 ax b 0.
