Quadratic Equations can be factored. Ax 2 bx c 0. This is just one method of solving quadratics you will encounter more throughout the course.
The quadratic formula x b b 2 4 a c 2 a is used to solve quadratic equations where a 0 polynomials with an order of 2 a x 2 b x c 0.
X b b2 4ac 2a. Ax 2 bx c 0. When using the quadratic formula you should be aware of three possibilities. Add the output of step 5 to both sides of the equation.
