having a hard time with a couple of problems please help
6-9=12 divided by y+5 y-5 y^2-25
On the first, two ways...
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.
take the square root of each side..
3x+5=sqrt (-8)= 2i sqrt2
then solve for x. It will be a complex number.
Multiply both sides by (y^2-25)
multiply out, gather terms and solve for y.
Thank you very much
