Explain one of the theorems that you would use to find the zero of higher degree polynomial

The zeros of a function f(x) are the values of x that cause f(x) to be equal to zero
One of methods to find the zeros of polynomial functions is The Factor Theorem

It is used to analyze polynomial equations. By it we can know that there is a relation between factors and zeros.

let:  f(x)=(x−c)q(x)+r(x)

If c is one of the zeros of the function , then the remainder r(x) = f(c) =0
 and f(x)=(x−c)q(x)+0 or f(x)=(x−c)q(x)

Notice, written in this form, x – c is a factor of f(x)
the conclusion is:  if c is one of the zeros of the function of f(x),
then x−c is a factor of f(x)

And vice versa , if (x−c) is a factor of f(x), then the remainder of the Division Algorithm f(x)=(x−c)q(x)+r(x)  is 0. This tells us that c is a zero for the function.

So, we can use the Factor Theorem to completely factor a polynomial of degree n into the product of n factors. Once the polynomial has been completely factored, we can easily determine the zeros of the polynomial.

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle
