(3x+12)/(x+4)=(4x^2+8x+18x^2)/(2x)
We move all terms to the left:
(3x+12)/(x+4)-((4x^2+8x+18x^2)/(2x))=0
Domain of the equation: 2x)!=0
x!=0/1
x!=0
x∈R
Domain of the equation: (x+4)!=0We calculate fractions
We move all terms containing x to the left, all other terms to the right
x!=-4
x∈R
(-((4x^2+8x+18x^2)*(x+4))/2x*x+(3x+12)*2x)/2x*x=0
