Question
Solve the equation
x1=−3,x2=0,x3=3
Alternative Form
x1≈−1.732051,x2=0,x3≈1.732051
Evaluate
3x2−x4=0
Factor the expression
x2(3−x2)=0
Separate the equation into 2 possible cases
x2=03−x2=0
The only way a power can be 0 is when the base equals 0
x=03−x2=0
Solve the equation
More Steps
Evaluate
3−x2=0
Move the constant to the right-hand side and change its sign
−x2=0−3
Removing 0 doesn't change the value,so remove it from the expression
−x2=−3
Change the signs on both sides of the equation
x2=3
Take the root of both sides of the equation and remember to use both positive and negative roots
x=±3
Separate the equation into 2 possible cases
x=3x=−3
x=0x=3x=−3
Solution
x1=−3,x2=0,x3=3
Alternative Form
