Answer 1

Answer:

if you have to express x in terms of k, you can do it. But if you have to find the values of x and k, you can't with the help of one equation only. It would be better if you posted actual problem so that correct steps might be decided.

to express x in terms of k....

7x^2 + 7x + k = 0

x^2 + x + k/7 = 0

x^2 + 2*x*1/2 + (1/2)^2 - 1/4 + k/7 = 0

(x + 1/2)^2 = 1/4 - k/7

x + 1/2 = +_√(1/4 - k/7)

x = -1/2 +_ √(1/4-k/7)

but I think this is not what you want.

Answer 2

Answer:

x= -k/7

, x= -k -1

Step-by-step explanation:

7x(x+1)+k=0

7x(x+1)=-k

then roots of x will be

first root

7x= -k

x= -k/7

second root

x+1= -k

x= -k -1
