Question

3. Simplify: 2x2(x + 2) - 3x (x2 - 3) - 5x(x + 5)​

Answer 1

Step-by-step explanation:

2x² ( x + 2 ) - 3x ( x² - 3 ) - 5x ( x + 5 )

2x² ( x + 2 ) = 2x³ + 4x²

- 3x ( x² - 3 ) = -3x³ + 9

- 5x ( x + 5 ) = -5x² - 25x

2x³ + 4x² - 3x³ + 9 - 5x² - 25x

2x³ - 3x³ + 4x² - 5x² - 25x + 9

- x³ - x² - 25x + 9

x ( - x² - x - 25 ) + 9
