Aquadratic equation ax squared plus bx plus c equals 0ax2+bx+c=0 has minus−55 and 11 as solutions. find the values of b and c if the value of a is 1.

The answer to the question is b=44 while c=-605

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
