The roots routine will return a column vector containing the roots of a polynomial. The general syntax is
z = roots(p)
where p is a vector containing the coefficients of the polynomial ordered in descending powers.
Given a vector
which describes a polynomial
we construct the companion matrix (which has a characteristic polynomial matching the polynomial described by p), and then find the eigenvalues of it (which are the roots of its characteristic polynomial)
Example
Here is an example of finding the roots to the polynomial
--> roots([1 -6 -72 -27])
ans =
12.1229
-5.7345
-0.3884
Answer:
<h2>x = -4 and y = -1 → (-4, -1)</h2>
Step-by-step explanation:
Answer:
find three consecutive even integers such that the sum of the second and third is equal to the first and third is 54 more than the second
Step-by-step explanation:
I think it’s 4 m because diameter is 2r
(8x)^2 = 1
64 x^2 = 1
x^2 = 1/64
x = 1/8
Answer
The positive value of x that makes the equation true is x = 1/8
