Let and be the roots of the equation and respectively. Find all possible real values for
I'm not sure how to do this question and not sure how to approach it.
Please help, BG
In a quadratic equation , m is the sum of the roots, and n is the product of the roots.
So from the second equation, we have (1). And (2)
And from the first one, we have (3) and (4)
From (4), we get c=0
Substituting in (3), we get b=0
Substituting in (1), we get d=0
Then, a can take any values you want...
