(7+-sqrt73)/-4

Explanation:

First, we must make the equation into the form of

ax^2+bx+c

in order to use the quadratic formula. Adding 10 to both sides of the equation gives us

2m^2-7m-3

This equation is in the form mentioned above and thus we can now use the quadratic equation to the roots

a= 2, b=-7, c=-3

We substitute these value into the equation to give us

(-(-7)+-sqrt((-7)^2-4(2)(-3)))/(-2*(2))

Thus, the roots to the equation 2m^2-7m-13=-10 would be

(7+-sqrt73)/-4
