Question

find the value of k of one root of eq 2x²-kx+3=0is 1/2​

Answer 1

Answer:

value of k = 7

Step-by-step explanation:

given that one root is 1/2 then

p(1/2) = 0

p(1/2) = 2(1/2)²- k(1/2) + 3

0 =2(1/4) -k/2 +3

0 = (2 - 2k + 12)/4

this implies that 2 - 2k + 12 = 0

14 - 2k = 0

2k = 14

k = 7.
