Move the 20 over to the left side so it is a quadratic equation.
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=361 is greater than zero. That means that there are two solutions:
can be factored:
Again, the answer is: 1.33333333333333, -5. Here's your graph:
