expand (30-x)^2

Solution

expand

(30 - x)^{2}

Solution

900 - 60 x + x^{2}

Solution steps

(30 - x)^{2}

Apply Perfect Square Formula:

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

(30 - x)^{2} = 3 0^{2} - 2 \cdot 30 x + x^{2}

= 3 0^{2} - 2 \cdot 30 x + x^{2}

Simplify

3 0^{2} - 2 \cdot 30 x + x^{2} : 900 - 60 x + x^{2}

= 900 - 60 x + x^{2}
