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

Solution

expand

2 (x + 1) (x - 2)

Solution

2 x^{2} - 2 x - 4

Solution steps

2 (x + 1) (x - 2)

Expand

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

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

Simplify

2 x^{2} + 2 (- x) + 2 (- 2) : 2 x^{2} - 2 x - 4

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