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 \cdot 2 x - 2 (- 3)

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

Simplify

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

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