You can put this solution on YOUR website!
Think: "difference of squares"
.
a%5E4-b%5E4
can be rewritten as:
%28a%5E2%29%5E2-%28b%5E2%29%5E2
which factors out as:
%28a%5E2-b%5E2%29%28a%5E2%2Bb%5E2%29
but, you're still not done. The term on the left is another "difference of squares":
%28a-b%29%28a%2Bb%29%28a%5E2%2Bb%5E2%29
