Identify the exponents on the variables in each term, and add them together to find the degree of each term.( 2x^(10)→ 10)( x^9→ 9)( x^6→ 6)The largest exponent is the degree of the polynomial.( 10)The maximum number of possible roots is the degree of ( 2x^(10)+x...
Hence the equation in the question becomes y^5-(32)(y^5)=31, i.e. (y^5-32)(y^5+1)=0. It follows that y may be 2 or -1. ●If x+2+√(x^2+4x+3) =2, we have x^2+4x+3 = (-x)^2, which gives x=-34. ●If x+2+√(x^2+4x+3) =-1, we have x^2+4x+...
The problem of finding the roots of a polynomial is equivalent to finding the eigenvalues of an upper Hessenberg matrix, which can be done with the QR algorithm. It is shown that the QR algorithm has considerable advantages over other standard algorithms to find the roots of a polynomial. 关键...
