expand 4(x-2)^2

Solution

expand

4 (x - 2)^{2}

Solution

4 x^{2} - 16 x + 16

Solution steps

4 (x - 2)^{2}

Expand

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

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

Apply the distributive law:

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

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

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

Simplify

4 x^{2} + 4 (- 4 x) + 4 \cdot 4 : 4 x^{2} - 16 x + 16

= 4 x^{2} - 16 x + 16
