1/5(30x+15)-9=-1/4(20x-20)
We move all terms to the left:
1/5(30x+15)-9-(-1/4(20x-20))=0
Domain of the equation: 5(30x+15)!=0
x∈R
Domain of the equation: 4(20x-20))!=0We calculate fractions
x∈R
(4x2/(5(30x+15)*4(20x-20)))+(-(-5x3)/(5(30x+15)*4(20x-20)))-9=0
We calculate terms in parentheses: +(4x2/(5(30x+15)*4(20x-20))), so:
4x2/(5(30x+15)*4(20x-20))
We multiply all the terms by the denominator
4x2
We add all the numbers together, and all the variables
4x^2
Back to the equation:
+(4x^2)
We calculate terms in parentheses: +(-(-5x3)/(5(30x+15)*4(20x-20))), so:
-(-5x3)/(5(30x+15)*4(20x-20))
We add all the numbers together, and all the variables
-(-5x^3)/(5(30x+15)*4(20x-20))
We multiply all the terms by the denominator
-(-5x^3)
We do not support expression: x^3
