2m4−11m3=0
Factor the expression
m3(2m−11)=0
Separate the equation into 2 possible cases
m3=02m−11=0
The only way a power can be 0 is when the base equals 0
m=02m−11=0
Solve the equation
More Steps

Evaluate
2m−11=0
Move the constant to the right-hand side and change its sign
2m=0+11
Removing 0 doesn't change the value,so remove it from the expression
2m=11
Divide both sides
22m=211
Divide the numbers
m=211
m=0m=211
Solution
m1=0,m2=211
