Solution

expand

(5 a - 6 b)^{2}

Solution

25 a^{2} - 60 ab + 36 b^{2}

Solution steps

(5 a - 6 b)^{2}

Apply Perfect Square Formula:

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

(5 a - 6 b)^{2} = (5 a)^{2} - 2 \cdot 5 a \cdot 6 b + (6 b)^{2}

= (5 a)^{2} - 2 \cdot 5 a \cdot 6 b + (6 b)^{2}

Simplify

(5 a)^{2} - 2 \cdot 5 a \cdot 6 b + (6 b)^{2} : 25 a^{2} - 60 ab + 36 b^{2}

= 25 a^{2} - 60 ab + 36 b^{2}
