Question
Solve the equation
x1=−32,x2=0
Alternative Form
x1≈−1.259921,x2=0
Evaluate
2x×1=−x4
Multiply the terms
2x=−x4
Add or subtract both sides
2x−(−x4)=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
2x+x4=0
Factor the expression
x(2+x3)=0
Separate the equation into 2 possible cases
x=02+x3=0
Solve the equation
More Steps
Evaluate
2+x3=0
Move the constant to the right-hand side and change its sign
x3=0−2
Removing 0 doesn't change the value,so remove it from the expression
x3=−2
Take the 3-th root on both sides of the equation
3x3=3−2
Calculate
x=3−2
An odd root of a negative radicand is always a negative
x=−32
