expand (n-5)^2

Solution

expand

(n - 5)^{2}

Solution

n^{2} - 10 n + 25

Solution steps

(n - 5)^{2}

Apply Perfect Square Formula:

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

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

= n^{2} - 2 n \cdot 5 + 5^{2}

Simplify

n^{2} - 2 n \cdot 5 + 5^{2} : n^{2} - 10 n + 25

= n^{2} - 10 n + 25
