Question
Solve the equation
x1=−2456,x2=0,x3=2456
Alternative Form
x1≈−1.367782,x2=0,x3≈1.367782
Evaluate
x×14=4x5
Use the commutative property to reorder the terms
14x=4x5
Add or subtract both sides
14x−4x5=0
Factor the expression
2x(7−2x4)=0
Divide both sides
x(7−2x4)=0
Separate the equation into 2 possible cases
x=07−2x4=0
Solve the equation
More Steps

Evaluate
7−2x4=0
Move the constant to the right-hand side and change its sign
−2x4=0−7
Removing 0 doesn't change the value,so remove it from the expression
−2x4=−7
Change the signs on both sides of the equation
2x4=7
Divide both sides
22x4=27
Divide the numbers
x4=27
Take the root of both sides of the equation and remember to use both positive and negative roots
x=±427
