Question

if a and b are the roots of the equation x2+ax-b is equal to 0 then find a and b​

Answer 1

Step-by-step explanation:

Sum of roots,

a+b = -a => 2a = -b

and,

product of roots, ab = -b => a = -1

So,

2a = -b => b = -2a = -2(-1) = 2

Answer 2

Answer:-a±$\sqrt{a^2-4b}$/2*1

Step-by-step explanation:

BY USING QUADRATIC EQUATION WE CAN FIND
