Question

Q4. If the product of zeros of the quadratic
polynomial f(x)=x2 - 4x +k is 3, find
the value of k.
Ok=3
k= -3
k=4
Ok=-1​

Answer 1

$a = 1$

$b = 4$

$c = k$

$\alpha \times \beta = 3$

As we know that ...

$\alpha \times \beta = \frac{c}{a}$

$3 = \frac{k}{1}$

$k = 3$

Answer 2

K=3

Here is your answer
