es para ahora , please , ayuden ​

Answer 1

Respuesta:

reducir : E=(m+6n)²_(m_6n)²_12mn

$E= (m+6n)^{2} - (m-6n)^{2} -12mn\\\\\\E= (m^{2} + 2(m)(6n)+(6n )^{2} ) - (m^{2} - 2(m)(-6n)+(-6n)^{2} ) - 12mn\\\\\\E= (m^{2}+12mn+36n^{2} ) - (m^{2}+12mn + 36n^{2}) - 12mn\\\\\\E =m^{2}+12mn+36n^{2} - m^{2}-12mn - 36n^{2} - 12mn\\\\E= - 12mn$
