Let me do the easiest. Notice that the first term for real x will always be positive, and the second term is positive, the sum is zero. So there are no real x.

(3x+5)^2=-8

take the square root of each side..

3x+5=sqrt (-8)= 2i sqrt2

then solve for x. It will be a complex number.

Second

Multiply both sides by (y^2-25)

6(y-5)-9(y+5)=12

multiply out, gather terms and solve for y.
