I'm having a hard time solving this question:

(2t-10)/t > t + 5

I multiplied by the squared lowest common denominator value and tried to solve for x, except that I cannot find any real solutions. I'm not sure what else to do?

The numerator has no real roots (the discriminant is negative), so we only have the critical number . So, test the expression on the two intervals:

and . If the expression is negative on either interval, then that interval is the solution.
