$-\left(x^2-4x-5\right)=0$
Learn how to solve quadratic equations problems step by step online. Solve the quadratic equation -x^2+4x+5=0. Factor the trinomial by -1 for an easier handling. Factor the trinomial -\left(x^2-4x-5\right) finding two numbers that multiply to form -5 and added form -4. Thus. Factor the trinomial \left(x^2-4x-5\right) finding two numbers that multiply to form -5 and added form -4.
