When deriving the quadratic formula, we first start with a generic quadratic formula using coefficients a, b and c and then derive the formula by completing the square. Substitute the given information into the equation. A {x^2} + bx + c = 0 ax2 + bx +c = 0 because the trinomial on the left side can’t be factored out easily.
