Find the roots
n=1
Evaluate
(n−1)(n−1×n−2)
To find the roots of the expression,set the expression equal to 0
(n−1)(n−1×n−2)=0
Any expression multiplied by 1 remains the same
(n−1)(n−n−2)=0
Subtract the terms
(n−1)(0−2)=0
Removing 0 doesn't change the value,so remove it from the expression
(n−1)(−2)=0
Multiply the terms
−2(n−1)=0
Change the sign
2(n−1)=0
Rewrite the expression
n−1=0
Move the constant to the right side
n=0+1
Solution
n=1
