Question

Are (x+y)2 and x2+y2 equal? why or why not?

Answer 1

They are not equal because if you distribute the 2 to the x and y on the 1st question you get 2x+2y which is not the same as x2+y2

Hope it helps comment for any questions!

Answer 2

no because you have to multiply (x+y) times (x+y) which gives a different answer
