(m+2n)²-(m-2n)²+m(m+2n)+2n(m+2n)+kmn

Respuesta:Explicación paso a paso:(m+2n)²-(m-2n)²+m(m+2n)+2n(m+2n)+kmn(m+2n)²-(m-2n)² + (m+2n)(m+2n) + kmn(m+2n)²-(m-2n)² + (m+2n)² + kmn2(m+2n)² - (m-2n)² + kmn2[m^2 + 4mn + 4n^2] - (m^2 - 4mn + 4n^2) + kmn2m^2 + 8mn + 8n^2 - m^2 + 4mn - 4n^2 + kmnm^2 + (12+k)mn + 4n^2para que sea un cuadrado perfecto k = - 8
