Solution

expand

(3 c - 5)^{2}

Solution

9 c^{2} - 30 c + 25

Solution steps

(3 c - 5)^{2}

Apply Perfect Square Formula:

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

(3 c - 5)^{2} = (3 c)^{2} - 2 \cdot 3 c \cdot 5 + 5^{2}

= (3 c)^{2} - 2 \cdot 3 c \cdot 5 + 5^{2}

Simplify

(3 c)^{2} - 2 \cdot 3 c \cdot 5 + 5^{2} : 9 c^{2} - 30 c + 25

= 9 c^{2} - 30 c + 25
