expand (1-5x)^2

Solution

expand

(1 - 5 x)^{2}

Solution

1 - 10 x + 25 x^{2}

Solution steps

(1 - 5 x)^{2}

Apply Perfect Square Formula:

(a - b)^{2} = a^{2} - 2 ab + b^{2}

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

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

Simplify

1^{2} - 2 \cdot 1 \cdot 5 x + (5 x)^{2} : 1 - 10 x + 25 x^{2}

= 1 - 10 x + 25 x^{2}
