Question

If x 3/2 = is a zero of the polynomial
2x² + kx - 12, then find the value of k.
​

Answer 1

Answer:k=5

Step-by-step explanation:

x=3/2

p(x)=2x^2+kx-12

putting 3/2 at place of x

p(3/2)=2(9/4)+k(3/2)-12

p(3/2)=9/2+3k/2-12

Acc. to Factor theoram 0=(9+3k-24)/2 0=(-15+3k)/2

0=-15+3k

15=3k

15/3=k

k=5
