When the product of factors equals 0,at least one factor is 0
m−1=05m+3=0
Solve the equation for m
More Steps

Evaluate
m−1=0
Move the constant to the right-hand side and change its sign
m=0+1
Removing 0 doesn't change the value,so remove it from the expression
m=1
m=15m+3=0
Solve the equation for m
More Steps

Evaluate
5m+3=0
Move the constant to the right-hand side and change its sign
5m=0−3
Removing 0 doesn't change the value,so remove it from the expression
5m=−3
Divide both sides
55m=5−3
Divide the numbers
m=5−3
Use b−a=−ba=−ba to rewrite the fraction
