Question

ayuden porfis urgente!!! :(

Answer 1

Respuesta:

$m= \frac{(a+b)^{2} +(a+c)^{2} +(b+c)^{2} }{a^{2} +b^{2} +c^{2} }$

$m= \frac{a^{2}+ 2 ab+b^{2} + a^{2}+2ac +c^{2} +b^{2} +2bc +c^{2} }{a^{2}+b^{2}c^{2} } \\\\m= \frac{2a^2+2ab+2ac+2b^2+2c^2+2bc}{a^2+b^2+c^2}$

$m\left(a^2+b^2+c^2\right)=\frac{2b^2+2ab+2bc+2a^2+2c^2+2ac}{a^2+b^2+c^2}\left(a^2+b^2+c^2\right)$

$m\left(a^2+b^2+c^2\right)=2b^2+2ab+2bc+2a^2+2c^2+2ac$
