Prove that x-y = √(x+y)^2-4xy?
Svetlanka [38]

Proved Below

\Longrightarrow x-y = \sqrt{(x+y)^2-4xy}

\Longrightarrow x-y = \sqrt{x^2+2(x)(y)+ y^2-4xy}

\Longrightarrow   x-y = \sqrt{x^2+2xy-4xy+y^2}

\Longrightarrow x-y = \sqrt{x^2-2xy+y^2}

\Longrightarrow x-y = \sqrt{(x-y)^2}

\Longrightarrow x-y =x-y
