18c4−144c3=0
Factor the expression
18c3(c−8)=0
Divide both sides
c3(c−8)=0
Separate the equation into 2 possible cases
c3=0c−8=0
The only way a power can be 0 is when the base equals 0
c=0c−8=0
Solve the equation
More Steps

Evaluate
c−8=0
Move the constant to the right-hand side and change its sign
c=0+8
Removing 0 doesn't change the value,so remove it from the expression
c=8
c=0c=8
Solution
c1=0,c2=8
