personally i do not know the details of these equations itself, but my friend seems to be having some trouble solving this question in a calc. textbook, lets see if you guys can shed some light on the question(adsbygoogle = window.adsbygoogle || []).push({});

1. The problem statement, all variables and given/known data

a^{3}-6a=b^{3}-6b

a^{4}-4a^{2}=b^{4}-4b^{2}

solve for a

2. Relevant equations

umm personally im not sure?

3. The attempt at a solution

no attempt can be written here, but apparently the answer is a^{2}=6
