Cosider the number 1,2,3,4,5,6,7,8,9 and 10.If 1 is added to each number the variance of the number so obtained is

In the algebraic expression a^2-3b^2+7b^2-9a^2+6a b+5, we have, a^2a n d-9a^2 as like terms. Also, -3b^2 and 7b^2 are like terms. But a^2,\ 7b^2 and 6a b are unlike terms.

Consider the numbers 1,2,3,4,5,6,7,8,9,10. If 1 is added to each number, the variance of the numbers so obtained is
