expand (4x-3y)^2

Solution

expand

(4 x - 3 y)^{2}

Solution

16 x^{2} - 24 x y + 9 y^{2}

Solution steps

(4 x - 3 y)^{2}

Apply Perfect Square Formula:

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

(4 x - 3 y)^{2} = (4 x)^{2} - 2 \cdot 4 x \cdot 3 y + (3 y)^{2}

= (4 x)^{2} - 2 \cdot 4 x \cdot 3 y + (3 y)^{2}

Simplify

(4 x)^{2} - 2 \cdot 4 x \cdot 3 y + (3 y)^{2} : 16 x^{2} - 24 x y + 9 y^{2}

= 16 x^{2} - 24 x y + 9 y^{2}
