expand-2x(x+1)(5-2x)

Solution

expand

- 2 x (x + 1) (5 - 2 x)

Solution

4 x^{3} - 6 x^{2} - 10 x

Solution steps

- 2 x (x + 1) (5 - 2 x)

Expand

- 2 x (x + 1) (5 - 2 x) : - 2 x (- 2 x^{2} + 3 x + 5)

= - 2 x (- 2 x^{2} + 3 x + 5)

Apply the distributive law:

m (a + b + c) = ma + mb + m c

- 2 x (- 2 x^{2} + 3 x + 5) = - 2 x (- 2 x^{2}) - 2 x \cdot 3 x - 2 x \cdot 5

= - 2 x (- 2 x^{2}) - 2 x \cdot 3 x - 2 x \cdot 5

Simplify

- 2 x (- 2 x^{2}) - 2 x \cdot 3 x - 2 x \cdot 5 : 4 x^{3} - 6 x^{2} - 10 x

= 4 x^{3} - 6 x^{2} - 10 x
