Question

If the sum of the zeros of the quadratic polynomial kx² ‒ 3x + 5 is 1, write the value of k.

Answer 1

Given: Sum of zeros of polynomial is kx² – 3x + 5 is 1.

We know that,

Sum of zeros = -(coefficient of x)/(coefficient of x²) = -(-3) / k = 3/k

From above results, we get

3/k = 1

Or k = 3
