Find a quadratic polynomial. The sum and product of whose zeroes are 3 and 2.
shadabaalam:
Plz verify your question once, "whose" word contradicts.
My answer is correct
Ofcourse it is correct, But what if the question is ' Find a quadratic polynomail whose zeros are 3 and 2, Then? So i just asked him to verify. Else both the solutions are Right.
Her by the way. And yes u r right it's not whose but the zeroes of its sum and product are 2 and 3
opps! i didn't noticed u are "her".
thats k

let the roots be a and b
a+b=3 ab=2
x^2-(a+b)x+ab
=x^2-3x+2
a+b=3 ab=2
x^2-(a+b)x+ab
=x^2-3x+2

Let one zero beα and other beβ
Then given that α+β=3 and α×β=2
Now (x-α)(x-β)=
-x(α+β)+α×β
Substitute the values α+β and α×β
-x(3)+2
-3x+2 is the qudratic expression
Then given that α+β=3 and α×β=2
Now (x-α)(x-β)=
Substitute the values α+β and α×β
