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=0 is zero! That means that there is only one solution:
Expression can be factored:
Again, the answer is: -0.75, -0.75. Here's your graph:
