If x=0 and x=3 then 3 divided by 2x to the second power minus 2 divided by x to the second power minus 3x

undefined in both cases.

Explanation:

1) Expression to evaluate:



2) You are asked to evaluate that expression for two different cases, x = 0 and x = 3.

3) First case: x = 0

The expression cannot be evaluated at x = 0, because the denominators (both  denominators) equal 0, and the division by 0 is not defined.

So, the answer is undefined.

4) Second case, x = 3

When you replace x = 3 you get:



Again, this result in a division by 0, so you conclude that it is undefined too.

The linear equation is: y=ax+b
