Answer:

heya mate ☺

(a + b)^{2}  - ( a- b) ^{2}  \\  = (a ^{2}  + 2ab + b ^{2} ) - (a ^{2}  - 2ab + b^{2} ) \\  = a ^{2}  + 2ab + b ^{2}  - a ^{2}  + 2ab - b ^{2}  \\  = 4ab \: (everything \: cancelled)

hope it helps u

Formula used :

  • ( a + b ) = a^2 + 2ab + b^2
  • ( a - b ) = a^2 - 2ab + b^2
