expand 3(x-2)^2

Solution

expand

3 (x - 2)^{2}

Solution

3 x^{2} - 12 x + 12

Solution steps

3 (x - 2)^{2}

Expand

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

= 3 (x^{2} - 4 x + 4)

Apply the distributive law:

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

3 (x^{2} - 4 x + 4) = 3 x^{2} + 3 (- 4 x) + 3 \cdot 4

= 3 x^{2} + 3 (- 4 x) + 3 \cdot 4

Simplify

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

= 3 x^{2} - 12 x + 12
