Question

if the equation x^2+px+q=0 and x^2+rs+s=0 have a common roots,prove that it is equal to

Answer 1

\[\frac{ ps-rq }{ q-s } \]
as well as
\[\frac{ q-s }{ r-p }\]
Find the remaining roots of the equations

Answer 2

I think it is x^2+rx+s=0

Answer 3

the second equation is right,correct sure or you have missed anything ?

Answer 4

yes @sauravshakya

Answer 5

how do you know if x1 and x2 are roots of a quadratic equation ax^2 +bx +c=0 how can you writing ,what will be x1 *x2 = and x1 + x2 =

can you answer this using a,b and c ?

Answer 6

Well roots of x^2+px+q=0 are

Answer 7

Can u tell me what are roots of x^2+rx+s=0
