Question

kx² - 11x - 6 = 0 is -1/2, then the value of k is​

Answer 1

Answer:

2

Step-by-step explanation:

if one of the root is -1/2

k (-1/2)^2 - 11(-1/2) - 6 = 0

k/4+11/2-6=0

multiply with 4 on both sides

4×k/4+4×11/2-4×6=4×0

k+22-24=0

k-2=0

k=2

write the question clearly and correctly get answer immediately

Answer 2

Answer:

if one of the root is -1/2

then K(-1/2)^2-11(-1/2)-6=0

Then K/4+11/2-6=0

then multiply the both sides by 4

4*k/4+4*11/2-4*6=4*0

k+22-24=0

k-2=0

K=2

Then the answer is K=2
