expand 4(2x-1)^2

Solution

expand

4 (2 x - 1)^{2}

Solution

16 x^{2} - 16 x + 4

Solution steps

4 (2 x - 1)^{2}

Expand

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

= 4 (4 x^{2} - 4 x + 1)

Apply the distributive law:

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

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

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

Simplify

4 \cdot 4 x^{2} + 4 (- 4 x) + 4 \cdot 1 : 16 x^{2} - 16 x + 4

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