Find the roots
n1=0,n2=2
Evaluate
(n−2)(n2)
To find the roots of the expression,set the expression equal to 0
(n−2)(n2)=0
Calculate
(n−2)n2=0
Multiply the terms
n2(n−2)=0
Separate the equation into 2 possible cases
n2=0n−2=0
The only way a power can be 0 is when the base equals 0
n=0n−2=0
Solve the equation
More Steps
Evaluate
n−2=0
Move the constant to the right-hand side and change its sign
n=0+2
Removing 0 doesn't change the value,so remove it from the expression
n=2
n=0n=2
Solution
n1=0,n2=2
