Question

if X equal to 1 by 2 is a zero of the polynomial 2x square + kx - 12 then find the value of k​

Answer 1

We have to do factorisation mate.

hope it helps

Answer 2

Step-by-step explanation:

if x is zero of polynomial then by putting value of it will be zero

2x²+kx-12=0

2(1/2)²+k(1/2)-12=0

1/2+k/2-12=0

1+k-24=0

so k=23
