expand (3-3x)^2

Solution

expand

(3 - 3 x)^{2}

Solution

9 - 18 x + 9 x^{2}

Solution steps

(3 - 3 x)^{2}

Apply Perfect Square Formula:

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

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

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

Simplify

3^{2} - 2 \cdot 3 \cdot 3 x + (3 x)^{2} : 9 - 18 x + 9 x^{2}

= 9 - 18 x + 9 x^{2}
