Answer 1

Derivation gives the nicest answer. Try derivating the expression.

Answer 2

Notice that the denominator of the last term can be factorised as follows:
\[\frac{3}{2x ^{2}-32}=\frac{3}{2(x+4)(x-4)}\]
Hint:This makes it simple to find the common denominator.

Answer 3

okay like one previous problem - 2x^2 - 32 = 2(x^2 - 16) --> can you use this?
