Answer 1

Answer:

a square+b square

Step-by-step explanation:

2àb-2ab

Answer 2

Answer:

Note first that |ab|=|a||b|≥ab and let A=|a|,B=|b| so that A2=a2,B2=b2. If A≠B, symmetry allows us to choose (rename) so that A>B>0. The cases of B=0 and A=B are straightforward to check.

Then

a2+b2=A2+B2=A2+AB−AB+B2=A(A+B)−B(A−B)>2AB−B(A−B)>2AB≥2ab
