expand (m+n+1)(m+n-1)

expand

(m + n + 1) (m + n - 1)

m^{2} + 2 mn + n^{2} - 1

Solution steps

(m + n + 1) (m + n - 1)

Distribute parentheses

= mm + mn + m (- 1) + nm + nn + n (- 1) + 1 \cdot m + 1 \cdot n + 1 \cdot (- 1)

Simplify

mm + mn + m (- 1) + nm + nn + n (- 1) + 1 \cdot m + 1 \cdot n + 1 \cdot (- 1) : m^{2} + 2 mn + n^{2} - 1

= m^{2} + 2 mn + n^{2} - 1
