expand-3(x-2)(x+4)

Solution

expand

- 3 (x - 2) (x + 4)

Solution

- 3 x^{2} - 6 x + 24

Solution steps

- 3 (x - 2) (x + 4)

Expand

- 3 (x - 2) (x + 4) : - 3 (x^{2} + 2 x - 8)

= - 3 (x^{2} + 2 x - 8)

Apply the distributive law:

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

- 3 (x^{2} + 2 x - 8) = - 3 x^{2} - 3 \cdot 2 x - 3 (- 8)

= - 3 x^{2} - 3 \cdot 2 x - 3 (- 8)

Simplify

- 3 x^{2} - 3 \cdot 2 x - 3 (- 8) : - 3 x^{2} - 6 x + 24

= - 3 x^{2} - 6 x + 24
