Hello CrackVerbal, I have the below doubt
after finding the roots of the equation and putting then on a line - How do we decide whether we start from "+" or "-" ,,,, in two of your example one line starts from "+" and one line starts with "-"
Kindly explain.
Hi,
We always start from the right and take that as +ve. Then we move to the left, taking alternate signs.
I mean right most will be +ve, then the one to its left will be -ve, then +ve , then -ve
