X-1/2X-3/8X=90
We move all terms to the left:
X-1/2X-3/8X-(90)=0
Domain of the equation: 2X!=0
X!=0/2
X!=0
X∈R
Domain of the equation: 8X!=0We calculate fractions
X!=0/8
X!=0
X∈R
X+(-8X)/16X^2+(-6X)/16X^2-90=0
We multiply all the terms by the denominator
X*16X^2+(-8X)+(-6X)-90*16X^2=0
Wy multiply elements
16X^3-1440X^2+(-8X)+(-6X)=0
We get rid of parentheses
16X^3-1440X^2-8X-6X=0
We do not support eXpression: X^3
