My calculator said it, I believe it, that settles it
You can put this solution on YOUR website! m^3-81m=0 with steps please;)
m^3 - 81m = 0
Factor out the Greatest Common Factor (GCF) = m
m(m^2 - 81) = 0
Factor a difference between two squares:
m(m + 9)(m - 9) = 0
Subproblem 1
Set the factor 'm' equal to zero and attempt to solve:
m = 0
Subproblem 2
m + 9 = 0
Subtract 9 from each side of the equation.
m + 9 - 9 = 0 - 9
Combine like terms:
9 - 9 = 0
0 - 9 = -9
m = -9
Subproblem 3
m - 9 = 0
Add 9 to each side of the equation.
m - 9 + 9 = 0 + 9
Combine like terms:
-9 + 9 = 0
0 + 9 = 9
m = 9
