How do I factor this expression? (x2 + 1) 1/2 + 2(x2 + 1)-1/2
I know that the answer is (x2 + 3) (x2 + 1) -1/2 but I don't know how to get to that answer. would appreciate help very much.
Thanks.
\(\displaystyle \left( {x^2 + 1} \right)^{1/2} + 2\left( {x^2 + 1} \right)^{ - 1/2}\)How do I factor this expression? (x2 + 1) 1/2 + 2(x2 + 1)-1/2
How do I factor this expression? .\(\displaystyle (x^2+ 1)^{\frac{1}{2}}+ 2(x^2+ 1)^{-\frac{1}{2}}\)
I know that the answer is: \(\displaystyle (x^2+ 3)(x^2+ 1)^{-\frac{1}{2}}\)
. . but I don't know how to get to that answer.
