expand (6x-3y)^2

Solution

expand

(6 x - 3 y)^{2}

Solution

36 x^{2} - 36 x y + 9 y^{2}

Solution steps

(6 x - 3 y)^{2}

Apply Perfect Square Formula:

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

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

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

Simplify

(6 x)^{2} - 2 \cdot 6 x \cdot 3 y + (3 y)^{2} : 36 x^{2} - 36 x y + 9 y^{2}

= 36 x^{2} - 36 x y + 9 y^{2}
