expand 2(x+1)(x-3)

Solution

expand

2 (x + 1) (x - 3)

Solution

2 x^{2} - 4 x - 6

Solution steps

2 (x + 1) (x - 3)

Expand

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

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

Apply the distributive law:

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

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

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

Simplify

2 x^{2} + 2 (- 2 x) + 2 (- 3) : 2 x^{2} - 4 x - 6

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