SOLVE quadratic equation (work shown, graph etc)
(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=4596 is greater than zero. That means that there are two solutions:
can be factored:
Again, the answer is: 1.32842392920746, -1.89985250063603. Here's your graph:
