  1. If α, β are the roots of the equation x2 - 5x + 6 = 0, construct a quadratic equation whose roots are
    1
    ,
    1
    .
    α
    β
    1. 6x2 + 5x - 1 = 0
    2. 6x2 - 5x - 1 = 0
    3. 6x2 - 5x + 1 = 0
    4. 6x2 + 5x + 1 = 0
Correct Option: C

As per the given above question , we can say that
Comparing x2 - 5x + 6 = 0 with ax2 - bx + c = 0 , we get
a = 1, b = - 5, c = 6

∴ α + β =
- b
=

Now, we are to form an equation whose roots are

So the required equation is
x2 − (sum of roots)x + (Product of roots) = 0

6x2 - 5x + 1 = 0
Thus , required equation is 6x2 - 5x + 1 = 0 .
