Question

x²(x-3y²)-xy(y²-2xy)-x(y³-5x²)​

Answer 1

Answer:

6x³ - 3x²y²

Step-by-step explanation:

x² (x - 3y²) - xy (y² - 2xy) - x (y³- 5x²)

= ​(x² *x) - (x² * 3y²) - (xy * y²) - (xy * - 2y) - (x * y³) - (x * - 5x²)

= x³ - 3x²y² - xy³ - (-2xy³) - xy³ - (-5x³)

= x³ - 3x²y² - xy³ + 2xy³ - xy³ + 5x³

= x³ + 5x³ - xy³ - xy³ - 3x²y² + 2xy³

= 6x³ - 2xy³ + 2xy³ - 3x²y²

= 6x³ - 3x²y²

Hope it helps!!
