Hi,
I'm doing h/w on factorising quadratics and I really can't work out how I'd go about factorising this expression:
p^2 - 8pq + 15q^2
Any ideas (+ explanations)?
Thanks!

If you can apply either the comparison test or limit comparison test then tell wheter it is convergent or divergent, if neither test can be applied to the series than say what test does
summation n=1 to infinity (cos(n)sqrt(n))/(9n+3)
summation n=1 to infinity ((ln(n))^2)/(n+9)
summation n=1 to infinity (9n^5-n^3+6n^(1/2))/(2n^7-n^2+2)
summation n=1 to infinity (9n^6)/(n^9+1)

The thief, however, did not notice, and grabbed 10 right shoes from the dispalay when the vendor was distracted. The thief quickly discovered that shoes are useless and destroyed the stolen merchandise. Later the thief was caught and the vendor demanded compensantion.

Venodor argues that becuase he lost 10 pair x $50 each, the thief must pay $500 in compensation. As evidence he entered all ten left shoes with price stickers attached.
Thief argues that he stole only half of merchandise and must repay only $250.

How should the judge rule?
