Question

One zero of the quadratic polynomial 2x²-8x-k is 5/2.then find the other zero and the value of k​

Answer 1

Heya

Let the other zero/root be A

We know that

A + 5/2 = 8/2

A = 4 - 5/2

A = 3/2

So, the other zero/root is 3/2.

We also know A × 5/2 = -K/2

3/2 × 5/2 = -K/2

K = -15/2

Have a great future ahead
