expand-3(x+1)^2

Solution

expand

- 3 (x + 1)^{2}

Solution

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

Solution steps

- 3 (x + 1)^{2}

Expand

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

= - 3 (x^{2} + 2 x + 1)

Apply the distributive law:

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

- 3 (x^{2} + 2 x + 1) = - 3 x^{2} - 3 \cdot 2 x - 3 \cdot 1

= - 3 x^{2} - 3 \cdot 2 x - 3 \cdot 1

Simplify

- 3 x^{2} - 3 \cdot 2 x - 3 \cdot 1 : - 3 x^{2} - 6 x - 3

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