Without solving the equation or factoring determine the solution to the equation x^2+4x-5=0.
.
how could that be? You can only determine the solution by solving it.
It's a parabola that opens upward, and solve it by Quadraric eqn you'll get the "X-Intercepts".
but by looking on the eqn, you know the Y-Intercept is -5, that is letting f%28x%29=0.
It looks like this:

Thank you,
