To simplify the square roots, we apply the square root to the number first, followed by the variable. So for 9x^2, we take the square root of 9 (which is 3), then the square root of x^2 (which is x).
The square root of (9x^2) is 3x. The square root of (18y^2) is (3sqrt2)y. Dividing the first term by the second term gives:x / y(sqrt2).If the final answer must be rationalized, it should be x(sqrt2) / 2y.

Answer:
3x^2-4x+20/x^2-5x .
Step-by-step explanation:
The given rational expression is:
3x/x-5 - 4/x
Hence to find the difference of the rational numbers we have to take the L.C.M of the denominators:
Thus the L.C.M of x-5 and x is (x-5)(x) and then solve for the numerator:
x(3x) - 4(x-5)/(x-5)(x)
Now solve the numerator and denominator:
3x^2-4x+20/x^2-5x
Thus the answer is 3x^2-4x+20/x^2-5x ....
