5c3
5c3−c=0
Factor the expression
c(5c2−1)=0
Separate the equation into 2 possible cases
c=05c2−1=0
Solve the equation
More Steps

Evaluate
5c2−1=0
Move the constant to the right-hand side and change its sign
5c2=0+1
Removing 0 doesn't change the value,so remove it from the expression
5c2=1
Divide both sides
55c2=51
Divide the numbers
c2=51
Take the root of both sides of the equation and remember to use both positive and negative roots
c=±51
