expand (10-x)^2

Solution

expand

(10 - x)^{2}

Solution

100 - 20 x + x^{2}

Solution steps

(10 - x)^{2}

Apply Perfect Square Formula:

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

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

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

Simplify

1 0^{2} - 2 \cdot 10 x + x^{2} : 100 - 20 x + x^{2}

= 100 - 20 x + x^{2}
