Question
Simplify the expression
210n2−210n
Evaluate
(n×1)(n−1)×210
Remove the parentheses
n×1×(n−1)×210
Rewrite the expression
n(n−1)×210
Use the commutative property to reorder the terms
210n(n−1)
Apply the distributive property
210n×n−210n×1
Multiply the terms
210n2−210n×1
Solution
210n2−210n
Show Solution

Find the roots
n1=0,n2=1
Evaluate
(n×1)(n−1)×210
To find the roots of the expression,set the expression equal to 0
(n×1)(n−1)×210=0
Any expression multiplied by 1 remains the same
n(n−1)×210=0
Use the commutative property to reorder the terms
210n(n−1)=0
Elimination the left coefficient
n(n−1)=0
Separate the equation into 2 possible cases
n=0n−1=0
Solve the equation

Evaluate
n−1=0
Move the constant to the right-hand side and change its sign
n=0+1
Removing 0 doesn't change the value,so remove it from the expression
n=1
n=0n=1
Solution
n1=0,n2=1
