Question

(1) One of the roots of the quadratic equation kx²-x- 12=0 is 3/2.Find the value of k.​

Answer 1

Answer:

k=6

Step-by-step explanation:

X=3/2

Kx^2-x-12=0

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

K(9/4)-3/2-12=0

k(9/4)-(3-24)/2=0

k=27/2*4/9

k=108/18

k=6

Answer 2

Answer:

k = 6

Step-by-step explanation:

put x = 3/2

k(3/2)² - 3/2 -12 = 0

9k/4 - 3/2 -12 = 0

9k/4 - 27/2 = 0

9k/4 = 27/2

k = 27/2 × 4/9

k = 6
