Solution

expand

(x - 3 y)^{2}

Solution

x^{2} - 6 x y + 9 y^{2}

Solution steps

(x - 3 y)^{2}

Apply Perfect Square Formula:

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

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

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

Simplify

x^{2} - 2 x \cdot 3 y + (3 y)^{2} : x^{2} - 6 x y + 9 y^{2}

= x^{2} - 6 x y + 9 y^{2}
