expand 4(x-1)^2

Solution

expand

4 (x - 1)^{2}

Solution

4 x^{2} - 8 x + 4

Solution steps

4 (x - 1)^{2}

Expand

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

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

Apply the distributive law:

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

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

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

Simplify

4 x^{2} + 4 (- 2 x) + 4 \cdot 1 : 4 x^{2} - 8 x + 4

= 4 x^{2} - 8 x + 4
