expand 5(1-x)^2

Solution

expand

5 (1 - x)^{2}

Solution

5 - 10 x + 5 x^{2}

Solution steps

5 (1 - x)^{2}

Expand

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

= 5 (1 - 2 x + x^{2})

Apply the distributive law:

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

5 (1 - 2 x + x^{2}) = 5 \cdot 1 + 5 (- 2 x) + 5 x^{2}

= 5 \cdot 1 + 5 (- 2 x) + 5 x^{2}

Simplify

5 \cdot 1 + 5 (- 2 x) + 5 x^{2} : 5 - 10 x + 5 x^{2}

= 5 - 10 x + 5 x^{2}
