Finding squares is most people's nightmare judging by the fact that not everyone is meant to be a math guru. Fortunately there are ways to find squares without the help of a calculator. This means that you will not have to memorize the "magic" keys on your calculator but namely know a trick or two that will stick to your head forever. Take our quiz and see if you can figure those tricks out.
(a+b) = a^2 + b^2 + 2*a*b
A^2 + b^2 + 2*a*b
(a+b)^2= a^2 + b^2 + 2*a*b
B^2= a^2 + b^2 + 2*a*b
