Rationalize the denominator:
2____
√[6] – √[5]
It came out fuzzy I will retype it
2/sqrt[6]-[5]
I think you mean

Multiply NUM and DEN by the conjugate of the DEN
The conjugate is , a sign change.
=
=

. Simplify the rational expression:
x2 – 3x – 10 find the gcf of the polynomial
x2 – x – 20
---------------
If you mean the GCF of the 2 polynomials:
x^2 – 3x – 10 = (x-5)*(x+2)
x^2 – x – 20 = (x-5)*(x+4)
------------
The only common factor is (x-5), so that's the GCF.
