If the roots are equal then the discriminant is 0.
Find the discriminant and solve the quadratic in respect to m.
Well to start I would distribute those and get:
(Set it equal to 0 since we need to find the roots.
Apply the quadratic equation:
How ever, we need these roots to be equal to m, therefore we set this equation to m:
And from there, solve for m . Hope this helps, Chad.
