Because it's not one of the options? Haha, I haven't got a clue.

The slope of the tangent line is 0 if p'(a)=0.

To find max/min values. And the slope of a constant function is 0.

I'm trying to get confirmation as to whether the answer and my thought process is correct and if not, how one would approach this question.

Sorry SammyS but the only thing that comes to mind is the function is a constant. Either that or the first step to find critical points. After looking at the problem again I've come to the conclusion that in order to fulfill the condition p(a)=0 only C) and E) can be true. Considering that...

Thanks for the replies. So this is the conclusion I've come to so far, p(x)=0 at x=a p'(x)=0 at x=a a is a root of the polynomial So, x2-a2=0 x2=a2 x=a Therefore, C) must be true. Am I in the right direction?

Homework Statement Let p be a polynomial function with p(a)= 0 =p'(a) for some real a. Which of the following must be true? A) p(x) is divisible by x+a B) p(x) is divisible by x^2+a^2 C) p(x) is divisible by x^2-a^2 D) p(x) is divisible by x^2+2ax+a^2 E) p(x) is divisible by x^2-2ax+a^2...

Thanks! I understand what to do now, its just basic substitution. Your post helped a lot!

Well I know there is an applied force and the force of friction working against it, but do i count in the force of gravity? And I don't see the reason why there are two different people, aren't the force due to friction and the mass going to stay the same no matter who pushes it?

I honestly can't figure out what to do. 3. Paul and Mintu are attempting to push a heavy fridge across the kitchen floor. When Paul pushes it with a muscular force of 550N, the fridge accelerates from rest to 28.0 cm/s in 3.5 s. When Mintu pushes it with a muscular force of 560N, the fridge...
