Question
Solve the equation
x1=−6,x2=0,x3=6
Alternative Form
x1≈−2.44949,x2=0,x3≈2.44949
Evaluate
5×2x3−6x=3x×18
Multiply the numbers
10x3−6x=3x×18
Multiply the terms
10x3−6x=54x
Move the expression to the left side
10x3−6x−54x=0
Subtract the terms
More Steps

Evaluate
−6x−54x
Collect like terms by calculating the sum or difference of their coefficients
(−6−54)x
Subtract the numbers
−60x
10x3−60x=0
Factor the expression
10x(x2−6)=0
Divide both sides
x(x2−6)=0
Separate the equation into 2 possible cases
x=0x2−6=0
Solve the equation
More Steps

Evaluate
x2−6=0
Move the constant to the right-hand side and change its sign
x2=0+6
Removing 0 doesn't change the value,so remove it from the expression
x2=6
Take the root of both sides of the equation and remember to use both positive and negative roots
x=±6
Separate the equation into 2 possible cases
x=6x=−6
x=0x=6x=−6
Solution
x1=−6,x2=0,x3=6
