x² + 5 x + 6 = x² + 2 x + 3 x + 6 = x ( x + 2 ) + 3 ( x + 2 ) = ( x + 3 ) ( x + 2 ) 2 x² + 7 x + 3 = 2 x² + 6 x + x + 3 = 2 x ( x + 3 ) + ( x + 3) = ( 2 x +1 ) ( x + 3 ) (x+2)(x+3)/ 15 x y² : ( x+3 ) ( 2 x + 1 ) / 5 x² y = [latex] \frac{( x +2 ) ( x + 3 ) }{15xy ^{2} } * \frac{5 x^{2} y}{(2x+1)(x+3)} = \\ =\frac{x(x+2)}{3y(2x+1) } [/latex] Answer:  B ) x times the quantity of x plus 2 over 3 y times the quantity 2 x plus 1
