Answer :
Answer:
m^2 - n^2
Step-by-step explanation:
(a+b)(a-b) = a^2 - b^2
using this identity:
(m+n)(m-n) = m^2 - n^2
Answer:
The combined form of \((m+n)(m-n)\) is \(m^2 - n^2\). This is obtained by applying the distributive property of multiplication over addition: \((m+n)(m-n) = m \cdot m - m \cdot n + n \cdot m - n \cdot n\), which simplifies to \(m^2 - mn + mn - n^2\). The terms \(mn\) and \(-mn\) cancel each other out, leaving \(m^2 - n^2\). This expression is known as the difference of squares and is a commonly used algebraic identity.
