Question

FIND THE VALUE OF X IF THE ARITHMETIC MEAN OF XSQUARE , 6X ,2 IS 6​

Answer 1

Answer:

2

Step-by-step explanation:

given that,

6 = (x^2+6x+2)/3

18 = x^2 + 6x + 2

18-2 = 16 = x^2 + 6x

let x = 1

16 = 1^2 + 6(1)

16 is not equals to 1 + 6

so,

let x= 2

16 = 2^2 + 6(2)

16 = 4 + 12 = 16

so x = 2
