Question
Solve the equation
x1=−30,x2=0,x3=30
Alternative Form
x1≈−5.477226,x2=0,x3≈5.477226
Evaluate
x2×x=30x
Multiply the terms
More Steps

Evaluate
x2×x
Use the product rule an×am=an+m to simplify the expression
x2+1
Add the numbers
x3
x3=30x
Move the expression to the left side
x3−30x=0
Factor the expression
x(x2−30)=0
Separate the equation into 2 possible cases
x=0x2−30=0
Solve the equation
More Steps

Evaluate
x2−30=0
Move the constant to the right-hand side and change its sign
x2=0+30
Removing 0 doesn't change the value,so remove it from the expression
x2=30
Take the root of both sides of the equation and remember to use both positive and negative roots
x=±30
Separate the equation into 2 possible cases
x=30x=−30
x=0x=30x=−30
Solution
x1=−30,x2=0,x3=30
Alternative Form
x1≈−5.477226,x2=0,x3≈5.477226
