1. Find the perfect square trinomial whose first two terms are q^2 + 3q= My answer is q^2 +3q+9.
2. Factor the perfect square trinomial. u^2-15u+50=
My answer is (u-5)(u+10)
3. Solve by completing the square. 3x^2+5x-1=0
My answer is {5-sqrt37/6, 5+sqrt37/6}
4. Solve: sqrt-x+7 = x-1
My answer is 0
5. Solve by factoring: q^2+4q+4=0
My answer is: {-2,2}

It doesn't seem right that so many homework questions be asked and answered here. Are we helping school kids cheat? Are we helping them to fail? Do they learn anything from the exercise? Should they work the problems out with their parents? With their peers?

Let m be an odd integer. Show m^(2^n) ≡1 mod 2^(n+2) for all positive natural numbers n.

So, I'm pretty sure that m^(2^n) is odd, while 2^(n+2) is even. But then I'm not sure how to go about showing this...

the degree of hot or cold, temperature or the degree of hot or cold and the temperature.


I would think it is the degree of hot or cold and the temperature but also know that the correct response may just be temperature.
