To calculate its location relative to a triangulated surface, the position of a horizontal torus on the z-axis must be found where it is tangent to a fixed line, and this requires the solution of a general quartic equation to be calculated.
Note as well that some of the zeroes may be complex. Also note that sometimes we have to factor the polynomial to get the roots and their multiplicity.
Show Solution First, notice that we really can say the other two since we know that this is a third degree polynomial and so by The Fundamental Theorem of Algebra we will have exactly 3 zeroes, with some repeats possible.
Do not worry about factoring anything like this. Also, recall that when we first looked at these we called a root like this a double root. This example leads us to several nice facts about polynomials. In each case we will simply write down the previously found zeroes and then go back to the factored form of the polynomial, look at the exponent on each term and give the multiplicity.
To do this we simply solve the following equation. Due to the nature of the mathematics on this site it is best views in landscape mode. This is because any factor that becomes 0 makes the whole expression 0.
So, to get the roots of a polynomial, we factor it and set the factors to 0. The same is true for the intersection of a line and a torus. Zeroes with a multiplicity of 1 are often called simple zeroes. This is the zero product property: To do this all we need to do is a quick synthetic division as follows.
In the next couple of sections we will need to find all the zeroes for a given polynomial. We can go back to the previous example and verify that this fact is true for the polynomials listed there. When we first looked at the zero factor property we saw that it said that if the product of two terms was zero then one of the terms had to be zero to start off with.
Again, the degree of a polynomial is the highest exponent if you look at all the terms you may have to add exponents, if you have a factored form.
In this section we have worked with polynomials that only have real zeroes but do not let that lead you to the idea that this theorem will only apply to real zeroes. The total of all the multiplicities of the factors is 6, which is the degree.
The leading coefficient of the polynomial is the number before the variable that has the highest exponent the highest degree.Write a polynomial function in standard form with the given zeros.
