प्रश्न
If the sum of the zeros of the quadratic polynomial f(x) = kx2 − 3x + 5 is 1, write the value of k.
उत्तर
We have to find the value of k, if the sum of the zeros of the quadratic polynomial f(x) = kx2 − 3x + 5 is 1 is 1
Given
Sum of the polynomial = 1
`(-text{Cofficient of x})/(text{Cofficient of }x^2)=1`
`-((-3)/k)=1`
`3 =1xxk`
`3 = k`
Hence, the value of k is = 3
