đây là tìm X hay j zậy bạn =D
Nghiệm to ko chắc lắm
ĐK : \(x\ne0;6;-4\)
\(-\frac{1}{39x\left(3-13\right)}+\frac{2}{-6\left(x-6\right)}=\frac{-3}{8\left(x+4\right)}\)
\(-\frac{1}{-390x}+\frac{2}{-6x+36}=\frac{-3}{8x+32}\)
\(\frac{\left(-6x+36\right)\left(8x+32\right)}{390x\left(-6x+36\right)\left(8x+32\right)}+\frac{780x\left(8x+32\right)}{390x\left(-6x+36\right)\left(8x+32\right)}=\frac{-1170x\left(-6x+36\right)}{\left(8x+32\right)\left(-6x+36\right)390x}\)
\(-828x^2+67176x+1152=0\)( vô nghiệm )
