Question

X square (3-5y square)+X(XY square-3x)-2y(y-2x square y)

Answer 1

Answer:

${x}^{2} (3 - 5 {y}^{2} ) + x(xy {}^{2} - 3x) - 2y(y - 2x {}^{2} y) \\ = 3 {x}^{2} - 5 {x}^{2} {y}^{2} + {x}^{2} {y}^{2} - 3 {x}^{2} - 2 {y}^{2} + 4 {x}^{2} {y}^{2} \\ = (3 {x}^{2} - 3 {x}^{2} ) + ( - 5 {x}^{2} {y}^{2} + {x}^{2} {y}^{2} + 4 {x}^{2} {y}^{2} ) - 2 {y}^{2} \\ = 0 + 0 - 2 {y}^{2} \\ = - 2 {y}^{2}$
