How would I solve this?
(a/b+1/a) (a-(a3)/(a2-b))

Question

anonymous · Answer

one of those is the answer

anonymous · Answer

So, solve what's in the parentheses first, then multiply them.

anonymous · Answer

What exactly are you having trouble with?

anonymous · Answer

So the first parentheses is (a2+b)/(ab) and the second one is (-ab)/(a2-b) ?

anonymous · Answer

One second

anonymous · Answer

Now, subtract the a^3 and you'll have ab. So, $$equation1(\frac{ a ^{2}+b }{ ab}) (\frac{ ab }{ a ^{2}+b })equation2$$
Now, notice that equation 1 has as its denominator ab, and equation 2 has as its numerator ab.... cross them out and replace them with 1 :D $$equation1(\frac{ a ^{2}+b }{ 1})(\frac{ 1}{a ^{2}+b})$$
Which, equals $$\frac{ a ^{2}+b }{ a ^{2}+b}$$
=1!
