The factor theorem states that for any polynomial function f(x), if f(a) = 0, then (x-a) is a factor of f(x).
Let f(x) = x3-2x2-8x-5. If (x+1) is a factor, then f(-1) = 0. (x+1 = x - (-1))
Input x = -1 into f: (-1)3-2(-1)2-8(-1)-5
f(-1) = -1 -2 + 8 - 5
f(-1) = 0.
Since f(-1) = 0, (x+1) is a factor of x3-2x2-8x-5.

How can you determine whether a polynomial equation has imaginary solutions?
To determine whether a polynomial equation has imaginary solutions, you must first identify what type of equation it is. If it is a quadratic equation, you can use the quadratic formula to solve for the solutions. If the equation is a cubic or higher order polynomial, you can use the Rational Root Theorem to determine if there are any imaginary solutions. The Rational Root Theorem states that if a polynomial equation has rational solutions, they must be a factor of the constant term divided by a factor of the leading coefficient. If there are no rational solutions, then the equation has imaginary solutions. To use the Rational Root Theorem, first list out all the possible rational solutions. Then, plug each possible rational solution into the equation and see if it is a solution. If there are any solutions, then the equation has imaginary solutions. If not, then there are no imaginary solutions.

Determine whether the Mean Value Theorem can be applied Then find all values of c that satisfy the theorem y equals 2 cos x plus cox 2x on 0 to π?
The mean value theorem can be applied to all continuous functions (or expressions), and so it is applicable here. There is no equation in te question and furthermore, no c (other than the first letter of cos in the expression so there are no values for c to satisfy anything!

Is 788 equal to788?
Absolutely! That is like asking whether the Pythagorean Theorem has to do with right triangles!
Did Pythagoras prove his own Theorem?
Yes, he must have proved his own Theorem otherwise it would not have been adopted by mathematicians across the globe. I'm sure you could test out the theorem: check whether c2 really does equal b2 + a2 in a manual measurement of a triangle; though this is less accurate and not as precise as the Theorem.
