Simplify the expression
m2−3m+2
Evaluate
(m−1)(m−2)
Apply the distributive property
m×m−m×2−m−(−2)
Multiply the terms
m2−m×2−m−(−2)
Use the commutative property to reorder the terms
m2−2m−m−(−2)
If a negative sign or a subtraction symbol appears outside parentheses, remove the parentheses and change the sign of every term within the parentheses
m2−2m−m+2

Find the roots
m1=1,m2=2
Evaluate
(m−1)(m−2)
To find the roots of the expression,set the expression equal to 0
(m−1)(m−2)=0
Separate the equation into 2 possible cases
m−1=0m−2=0
Solve the equation
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=1m−2=0
Solve the equation
More Steps
Evaluate
m−2=0
Move the constant to the right-hand side and change its sign
m=0+2
Removing 0 doesn't change the value,so remove it from the expression
m=2
m=1m=2
Solution
m1=1,m2=2
