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=49 is greater than zero. That means that there are two solutions:
.
Quadratic expression
can be factored:
Again, the answer is: 0.5, -3. Here's your graph:
.
