State whether the following equations are sometimes, always or never true. a) a^22abb^2= (ab)^2, bis not equal to 0 b) a^2+ b^2= (a+b)(a+b) c) a^2b^2= a^22ab+b^2 d) (a=b)^2 = a^2+2ab+b^2 I don't understand what these

Why does this happen? A=3 and b=2 A+b=c is the equation. Multiplying both sides of the equation makes the equation a^2+2ab+b^2 which is equal to a^2+abac=abb^2+bc Dividing by (a+bc) we find a=b or 3=2 Why?

if a+b=1 and a squared + b squared=2 what does a to the 3rd + b to the 3rd equal? If b is 1, b cubed is one. That would work for the first half, but doesn't extend to a to the 3rd+b to the 3rd and what weould 2 squard be? Thank
