Solution

expand

(8 - 4 b)^{2}

Solution

64 - 64 b + 16 b^{2}

Solution steps

(8 - 4 b)^{2}

Apply Perfect Square Formula:

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

(8 - 4 b)^{2} = 8^{2} - 2 \cdot 8 \cdot 4 b + (4 b)^{2}

= 8^{2} - 2 \cdot 8 \cdot 4 b + (4 b)^{2}

Simplify

8^{2} - 2 \cdot 8 \cdot 4 b + (4 b)^{2} : 64 - 64 b + 16 b^{2}

= 64 - 64 b + 16 b^{2}
