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

Solution

expand

- 2 (x + 1) \cdot (2 - x)

Solution

2 x^{2} - 2 x - 4

Solution steps

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

Expand

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

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

Apply the distributive law:

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

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

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

Simplify

- 2 (- x^{2}) - 2 x - 2 \cdot 2 : 2 x^{2} - 2 x - 4

= 2 x^{2} - 2 x - 4
