Question

if a and b are the roots of the equation x^2+ax-b then find the value of a and b​

Answer 1

Answer:

answer is A:--1. and B:-2

Step-by-step explanation:

Given a and b are the roots of equation x^2+ax-b

a+b=-b/a

a+b=-a

b=-2a

ab=c/a

ab=-b (both b got cancelled)

a=-1

a=-1,b=-2a = -2x-1

b =2.

Some note:-

a,b are roots of equation, if a,b are of the same equation then A=a,B=b or vice versa....

Hope this helps Thank you.......
