I assume you menat to include someting on the right side of the equality. I will further assume that was 0
Thus x = -1/5 or x = -4
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: -0.2, -4. Here's your graph:
