Question
Solve the equation
x1=−54875,x2=0,x3=54875
Alternative Form
x1≈−1.087757,x2=0,x3≈1.087757
Evaluate
x×14=10x5
Use the commutative property to reorder the terms
14x=10x5
Add or subtract both sides
14x−10x5=0
Factor the expression
2x(7−5x4)=0
Divide both sides
x(7−5x4)=0
Separate the equation into 2 possible cases
x=07−5x4=0
Solve the equation
More Steps

Evaluate
7−5x4=0
Move the constant to the right-hand side and change its sign
−5x4=0−7
Removing 0 doesn't change the value,so remove it from the expression
−5x4=−7
Change the signs on both sides of the equation
5x4=7
Divide both sides
55x4=57
Divide the numbers
x4=57
Take the root of both sides of the equation and remember to use both positive and negative roots
x=±457
