CAS: solve without simplify fails
Please excuse me if this has been answered here before. I couldn't find any thread referring to this yet.

In CAS:
solve((x-7)*(x+7) = x^2 - 49) --> [undef]

solve(simplify((x-7)*(x+7) = x^2 - 49)) --> {x}

Firmware: 20160829 (10637)

Please understand that for pupils it is hard to enter nested commands. Is there any other way to solve this directly?

Many thanks in advance.
Bruno
