Question

If x= -1/2 is a root of the equation 3x²+2kx – 3 =0 then the value of k is​

Answer 1

Step-by-step explanation:

3x²+2kx-3=0

3(-1/2)²+2k×(-1/2)-3=0

-3/4-k-3=0

k=-15/4

Answer 2

Answer is 9

hope it helps you

please follow me please please

mark my answer as brainliest then follow me please please please

p(x) = x²-kx +2=0

x = -1/2

p(-1/2) = (-1/2)²-k×-1/2 +2=0

1/7+k/2 +2=0

1+8 b+8 = 0 /4

2b+9=0

k=-9/2

value of k /8 =9/2/2

=2/5×2/1=9/2×1

cut both 2

k/2 = 9
