To solve a 2 nd order equation like ax² bx c 0 enter or replace the coefficients a b and c. Solve both equations y 8 and y 8. To solve a quadratic equation by factoring Put all terms on one side of the equal sign leaving zero on the other side.
Solve both equations y 8 and y 8.
5 x2 4x 8. -b b²-4ac 2a. Y4 4y2 4 2y4 y2 y4 3y2 4 0 y2 4y2 1 0. This allows us to separate the factors and set them equal to 0 individually to find the solution s to the equation.
