Question

verify the relationship between the zeros and coefficients of the following polynomials. (a)x²+11x+18 (b)2x³+x-6 ​

Answer 1

Answer:

Let a, b, c be the roots of the equation x^2 +11x+18

a+b=-11

ab=18

Let a, b, c are the roots of the equation is 2x^3 +x-6

a+b+c= 0

ab+bc+ca=1/2

abc=3
