Answer 1

As, in 3rd step
${a}^{2} + {b}^{2} + 2ab = (a + b) {}^{2}$
${a}^{2} + {b}^{2} = (a + b) {}^{2} - 2ab$
In the last step it is( a+b) (a-b) =a square - b square
(.......) 2 - x square y square
=(.......) square - (xy) square
= Identity to be use is a square - b square =(a+b) (a-b)
Then, (....... +xy) (...... - xy)
