Question
Solve the equation
x1=−1,x2≈1.297979
Evaluate
5x4−4x=9
Move the expression to the left side
5x4−4x−9=0
Factor the expression
(x+1)(5x3−5x2+5x−9)=0
Separate the equation into 2 possible cases
x+1=05x3−5x2+5x−9=0
Solve the equation
More Steps
Evaluate
x+1=0
Move the constant to the right-hand side and change its sign
x=0−1
Removing 0 doesn't change the value,so remove it from the expression
x=−1
x=−15x3−5x2+5x−9=0
