Question

( 5xy² +9xy - x²y²) : (-xy)

Answer 1

\(\dfrac{5xy^2+9xy-x^2y^2}{-xy}==\dfrac{xy\left(5y+9-xy\right)}{-xy}=\dfrac{5y+9-xy}{-1}=-5y-9+xy\)

Answer 2

\(\left(5xy^2+9xy-x^2y^2\right):\left(-xy\right)\)

\(=xy\left(5y+9-xy\right):\left(-xy\right)\)

\(=-\left(5y+9-xy\right)\)

\(=-5y-9+xy\)

Answer 3

=-5y-9+xy
