Step-by-step explanation:

[yx + (y + 2)(x + 2)] – [y(x + 2) + (y + 2)x] [(yx + yx + 2x + 2y + 4) – ( yx + 2y + xy + 2x)] = 4 (iii) If we take the square of 16 numbers. We get the form as The difference of the angle to angle sum is , [yx + (y + 3)(x + 3)] – [y(x + 3) + (y + 3)x] [yx + yx + 3x + 3y + 9] – [yx + 3y + yx + 3x] = 9Read more on Sarthaks.com - https://www.sarthaks.com/1392090/instead-numbers-take-square-nine-numbers-shown-previous-table-mark-numbers-four-corners?show=1392102#a1392102
