Question
Simplify the expression
4m2−2m
Evaluate
(2m×1)(2m−1)
Remove the parentheses
2m×1×(2m−1)
Any expression multiplied by 1 remains the same
2m(2m−1)
Apply the distributive property
2m×2m−2m×1
Multiply the terms
More Steps

Evaluate
2m×2m
Multiply the numbers
4m×m
Multiply the terms
4m2
4m2−2m×1
Solution
4m2−2m

Find the roots
m1=0,m2=21
Alternative Form
m1=0,m2=0.5
Evaluate
(2m×1)(2m−1)
To find the roots of the expression,set the expression equal to 0
(2m×1)(2m−1)=0
Multiply the terms
2m(2m−1)=0
Elimination the left coefficient
m(2m−1)=0
Separate the equation into 2 possible cases
m=02m−1=0
Solve the equation
More Steps

Evaluate
2m−1=0
Move the constant to the right-hand side and change its sign
2m=0+1
Removing 0 doesn't change the value,so remove it from the expression
2m=1
Divide both sides
22m=21
Divide the numbers
m=21
m=0m=21
Solution
m1=0,m2=21
Alternative Form
m1=0,m2=0.5
