expand-4(x-4)(x-3)

Solution

expand

- 4 (x - 4) (x - 3)

Solution

- 4 x^{2} + 28 x - 48

Solution steps

- 4 (x - 4) (x - 3)

Expand

- 4 (x - 4) (x - 3) : - 4 (x^{2} - 7 x + 12)

= - 4 (x^{2} - 7 x + 12)

Apply the distributive law:

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

- 4 (x^{2} - 7 x + 12) = - 4 x^{2} - 4 (- 7 x) - 4 \cdot 12

= - 4 x^{2} - 4 (- 7 x) - 4 \cdot 12

Simplify

- 4 x^{2} - 4 (- 7 x) - 4 \cdot 12 : - 4 x^{2} + 28 x - 48

= - 4 x^{2} + 28 x - 48
