expand (2x-10)^2

Solution

expand

(2 x - 10)^{2}

Solution

4 x^{2} - 40 x + 100

Solution steps

(2 x - 10)^{2}

Apply Perfect Square Formula:

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

(2 x - 10)^{2} = (2 x)^{2} - 2 \cdot 2 x \cdot 10 + 1 0^{2}

= (2 x)^{2} - 2 \cdot 2 x \cdot 10 + 1 0^{2}

Simplify

(2 x)^{2} - 2 \cdot 2 x \cdot 10 + 1 0^{2} : 4 x^{2} - 40 x + 100

= 4 x^{2} - 40 x + 100
