**Precalculus(URGENT)**

The inequality holds wherever the numerator and denominator have opposite sign. Figure out where that happens. x=2 is in the domain of validity. So is x=0 We don't do graphs, but if you draw you own you will get a better understanding of how to do problems like this.

**Precalculus(URGENT)**

I suppose by "disciminant" you mean the term b^2 - 4ac. To find out what a, b and c are, rewrite the equati9n in the form ax^2 + bx + c = 0 That means a=7, b=-2 and c=5. That makes discriminant a large negative number. The two roots are imaginary.
