expand (6a-7b)^2

Solution

expand

(6 a - 7 b)^{2}

Solution

36 a^{2} - 84 ab + 49 b^{2}

Solution steps

(6 a - 7 b)^{2}

Apply Perfect Square Formula:

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

(6 a - 7 b)^{2} = (6 a)^{2} - 2 \cdot 6 a \cdot 7 b + (7 b)^{2}

= (6 a)^{2} - 2 \cdot 6 a \cdot 7 b + (7 b)^{2}

Simplify

(6 a)^{2} - 2 \cdot 6 a \cdot 7 b + (7 b)^{2} : 36 a^{2} - 84 ab + 49 b^{2}

= 36 a^{2} - 84 ab + 49 b^{2}
