expand (3n-p)^2

Solution

expand

(3 n - p)^{2}

Solution

9 n^{2} - 6 n p + p^{2}

Solution steps

(3 n - p)^{2}

Apply Perfect Square Formula:

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

(3 n - p)^{2} = (3 n)^{2} - 2 \cdot 3 n p + p^{2}

= (3 n)^{2} - 2 \cdot 3 n p + p^{2}

Simplify

(3 n)^{2} - 2 \cdot 3 n p + p^{2} : 9 n^{2} - 6 n p + p^{2}

= 9 n^{2} - 6 n p + p^{2}
