x5−71x×9=0
Multiply the terms
x5−639x=0
Factor the expression
x(x4−639)=0
Separate the equation into 2 possible cases
x=0x4−639=0
Solve the equation
More Steps
Evaluate
x4−639=0
Move the constant to the right-hand side and change its sign
x4=0+639
Removing 0 doesn't change the value,so remove it from the expression
x4=639
Take the root of both sides of the equation and remember to use both positive and negative roots
x=±4639
Separate the equation into 2 possible cases
x=4639x=−4639
x=0x=4639x=−4639
Solution
x1=−4639,x2=0,x3=4639
Alternative Form
