A worksheet asks for ^2 A A + ^2 A A + 2 A A written as one simple expression. Which is it?

Question

Accepted Answer

A + A. Put everything over A A : ^3 A/ A + ^3 A/ A + 2 A A = ^4 A + ^4 A + 2 ^2 A ^2 A/ A A = ( ^2 A + ^2 A)^2/ A A = 1/ A A = A + A . Answering 1 forgets that the denominator A A does not cancel away. Check at A = 30°: the expression is about 2.309 and 30^° + 30^° 2.309 .
