Question

me ajudem nessa (25x²y-40y²):(-5y)

Answer 1

Oie, Td Bom?!

$= \frac{25x {}^{2} y - 40y {}^{2} }{ - 5y}$

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

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

$= - (5x {}^{2} - 8y)$

$= - 5x {}^{2} + 8y$

Resposta:

$(25 {x}^{2} y-40 {y}^{2} ):(-5y) \\ \frac{25 {x}^{2} y - 40 {y}^{2} }{ - 5y} \\ - (5 {x}^{2} - 8y) \\ - 5 {x}^{2} + 8y$
