To solve for x we can use the quadratic formula:
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=48 is greater than zero. That means that there are two solutions:
can be factored:
Again, the answer is: -0.845299461620749, -3.15470053837925. Here's your graph:
