expand (18-x)^2

Solution

expand

(18 - x)^{2}

Solution

324 - 36 x + x^{2}

Solution steps

(18 - x)^{2}

Apply Perfect Square Formula:

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

(18 - x)^{2} = 1 8^{2} - 2 \cdot 18 x + x^{2}

= 1 8^{2} - 2 \cdot 18 x + x^{2}

Simplify

1 8^{2} - 2 \cdot 18 x + x^{2} : 324 - 36 x + x^{2}

= 324 - 36 x + x^{2}
