Question

Simplify it→3x²(3y²+2)-x(x-2xy²)+y(2x²y-2y)​

Answer 1

Step-by-step explanation:

$3 {x}^{2} (3 {y}^{2} + 2) - x(x - 2x {y}^{2} ) + y(2 {x}^{2} y - 2y) \\ = 9 {x}^{2} {y}^{2} + 6 {x}^{2} - {x}^{2} + 2 {x}^{2} {y}^{2} + 2 {x}^{2} {y}^{2} - 2 {y}^{2} \\ = 13 {x}^{2} {y}^{2} + 5 {x}^{2} - 2 {y}^{2} \\ = 5 {x }^{2} + 13 {x}^{2} {y}^{2} - 2 {y}^{2}$

Answer 2

solve:.3x^2(3y^2+2)-x(x-2xy^2)+y(2x^2y-2y)

9x^2y^2+6x^2-x^2+2x^2y^2+2x^2y^2-2y^2

13x^2y^2+5x^2-2y^2 is the correct answer
