You have identified correctly that the x co-ordinatea of theOriginally Posted byx-disturbed-x

points of intersection of A and B are the solutions of

so now find those solutions, let's call them and , and we

will assume that , (they are not equal as the LHS

of the equation is not the square of a single linear factor).

Then from what we are told we know that the

x co-ordinate of A is , and the x co-ordinate of B

is .

To find the y co-ordinates of A and B respectivly we now substitute

and into
