Question
Solve the equation
x1=−42,x2=0,x3=42
Alternative Form
x1≈−1.189207,x2=0,x3≈1.189207
Evaluate
4x2=2x6
Add or subtract both sides
4x2−2x6=0
Factor the expression
2x2(2−x4)=0
Divide both sides
x2(2−x4)=0
Separate the equation into 2 possible cases
x2=02−x4=0
The only way a power can be 0 is when the base equals 0
x=02−x4=0
Solve the equation
More Steps
Evaluate
2−x4=0
Move the constant to the right-hand side and change its sign
−x4=0−2
Removing 0 doesn't change the value,so remove it from the expression
−x4=−2
Change the signs on both sides of the equation
x4=2
Take the root of both sides of the equation and remember to use both positive and negative roots
x=±42
Separate the equation into 2 possible cases
x=42x=−42
x=0x=42x=−42
