(m + n)/(m - n) + (m - n)(m + n)
(m + n)(m + n)/(m + n)(m - n) + (m - n)(m - n)/(m + n)(m - n) {got common denominator of (m + n)(m - n)}
= (m² + 2mn + n²)/(m + n)(m - n) + (m² - 2mn + n²)/(m + n)(m - n) {multiplied in numerators}
= (2m² + 2n²)/(m + n)(m - n) {combined numerators over common denominator}
