SOLVE quadratic equation with variable
(in our case
) has the following solutons:
For these solutions to exist, the
should not be a negative number.
First, we need to compute the discriminant
Discriminant d=1 is greater than zero. That means that there are two solutions:
can be factored:
Again, the answer is: -2, -1. Here's your graph:
