Question

(ii) -6x²(xy+2y²) - 3y²(2x²+y)
pls help ​

Answer 1

Step-by-step explanation:

-6x²(xy+2y²)-3y²(2x²+y)

-6x³y-12x²y²-6x²y²-3y³

-6x³y-18x²y²-3y³

Answer 2

AnsweR :

$\sf \huge \bold{ {6x}^{3} - {18x}^{2} {y}^{2} - {3y}^{3} }$

SolutioN :

$\sf - {6x}^{2} (xy + {2y}^{2} ) - {3y}^{2} ( {2x}^{2} + y) \\ \\ \sf = { - 6x}^{3} y - {12x}^{2} {y}^{2} - 6 {x}^{2} {y}^{2} - {3y}^{3} \\ \\ \sf = {6x}^{3} - {18x}^{2} {y}^{2} - {3y}^{3}$
