Question

- 6 x ^ { 2 } ( x y + 2 y ^ { 2 } ) - 3 y ^ { 2 } ( 2 x ^ { 2 } + y )simplify​

Answer 1

Answer:

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