Consequently it involves solving a top half -b - the square root of b2 4ac and then dividing the top half by 2a. First we bring the equation to the form ax²bxc0 where a b and c are coefficients. Answer1 Mathsqrt bb-4ac.
Get the quadratic equation in the form ax2 bx c 0.
In order to begin you must memorise the quadratic formula because it will rarely be provided for you. Isolate the term c to right. To use the quadratic formula we follow these steps. The Quadratic Formula uses the a b and c from ax 2 bx c where a b and c are just numbers.
