Question

state whether x = -k/2 is the solution of the quadratic equation
2x^2+(k-6)x-3k=0
can anyone pls send the soln..​

Answer 1

Step-by-step explanation:

ggggggggggggtttggggggghhh

Answer 2

Step-by-step explanation:

x=-k/2

Now,

2x^2 +(k-6)-3k=0

2(-k/2)^2+(-k/2-6)-3(-k/2)=0

2(k/4)+(-k-12/2)+3k/2=0

2k/4+(-k-12+3k/2)=0

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

k+2k-12/2=0

3k-12/2=0

3k-12=0

3k=12

k=12/3

k=4

HERE IS UR ANSWER
