Question
Solve the equation
x=0
Evaluate
3x=−3x3×6
Multiply the terms
3x=−18x3
Add or subtract both sides
3x−(−18x3)=0
If a negative sign or a subtraction symbol appears outside parentheses, remove the parentheses and change the sign of every term within the parentheses
3x+18x3=0
Factor the expression
3x(1+6x2)=0
Divide both sides
x(1+6x2)=0
Separate the equation into 2 possible cases
x=01+6x2=0
Solve the equation

Evaluate
1+6x2=0
Move the constant to the right-hand side and change its sign
6x2=0−1
Removing 0 doesn't change the value,so remove it from the expression
6x2=−1
Since the left-hand side is always positive or 0,and the right-hand side is always negative,the statement is false for any value of x
x∈/R
x=0x∈/R
Solution
x=0
