Solved by pluggable solver: SOLVE quadratic equation with variable

Quadratic equation (in our case ) has the following solutons:

For these solutions to exist, the discriminant should not be a negative number.

First, we need to compute the discriminant : .

Discriminant d=225 is greater than zero. That means that there are two solutions: .

Quadratic expression can be factored:

Again, the answer is: 5, -2.5. Here's your graph:

2v^2-5v-25=0
(2v+5)(v-5)=0
2v+5=0
2v=-5
v=-5/2
v=-2.5 ans.
v-5=0
v=5
