Question

find the value of k if 2 x - 3 is a factor of 2 X square + kx square + X + 12​

Answer 1

hey! here is ur answer.

hope it helps u!!

Answer 2

Answer:

2x-3=0

2x=3

x=3/2

2(3/2)^2 + k(3/2)^2 +(3/2) +12 = 0

(9/2) + (9/4)*k +(3/2) + 12 = 0

18+9k+6+12/4 = 0

72 + 9k = 0

9k = -72

K = -72/9

K = -8
