Question

Calcule: ( 40x³y² - 5x²y³ ) : ( - 10xy )​

Answer 1

Oie, Td Bom?!

$= \frac{40x {}^{3}y {}^{2} - 5x {}^{2} y {}^{3} }{ - 10xy}$

$= \frac{5xy \: . \: (8x {}^{2} y - xy {}^{2}) }{ - 10xy}$

$= \frac{8x {}^{2}y - xy {}^{2} }{ - 2}$

$= \frac{ - (xy {}^{2} - 8x {}^{2}y) }{ - 2}$

$= \frac{xy {}^{2} - 8x {}^{2} y }{2}$
