expand-2(x-1)^2

Solution

expand

- 2 (x - 1)^{2}

Solution

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

Solution steps

- 2 (x - 1)^{2}

Expand

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

= - 2 (x^{2} - 2 x + 1)

Apply the distributive law:

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

- 2 (x^{2} - 2 x + 1) = - 2 x^{2} - 2 (- 2 x) - 2 \cdot 1

= - 2 x^{2} - 2 (- 2 x) - 2 \cdot 1

Simplify

- 2 x^{2} - 2 (- 2 x) - 2 \cdot 1 : - 2 x^{2} + 4 x - 2

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