#### Are the following pairs of sets equal? Give reasons. A = 2, 3, B = x: x is a solution of x^2+5x+6=0

$A=\left\{2, 3\right \}\\*B=x^2+5x+6=0\\*\Rightarrow x^2+3x+2x+6=0\\* \Rightarrow x(x+3)+2(x+3)=0\\*\Rightarrow (x+3)(x+2)=0\\*\Rightarrow x= -2\;and\;-3\\*\Rightarrow \left\{-2,-3\right \}\\*Since,\;A\; and\; B\; do \;not\; have\; exactly\; same\; elements\; hence\; they\; are\; not\; equal.$
