expand-2(x-3)^2

Solution

expand

- 2 (x - 3)^{2}

Solution

- 2 x^{2} + 12 x - 18

Solution steps

- 2 (x - 3)^{2}

Expand

(x - 3)^{2} : x^{2} - 6 x + 9

= - 2 (x^{2} - 6 x + 9)

Apply the distributive law:

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

- 2 (x^{2} - 6 x + 9) = - 2 x^{2} - 2 (- 6 x) - 2 \cdot 9

= - 2 x^{2} - 2 (- 6 x) - 2 \cdot 9

Simplify

- 2 x^{2} - 2 (- 6 x) - 2 \cdot 9 : - 2 x^{2} + 12 x - 18

= - 2 x^{2} + 12 x - 18
