Question

Calculate the restricted value, or values, for the equation below.

(3/x+2) + (1/2x) =4/x+2

Answer 1

denominator can't be zero

Answer 2

x cannot be equal to zero
for the value of x you can solve this quadratic and by chance if you get 0 as answer you can leave it aside

Answer 3

\[\frac{ 3 }{ x+2}+\frac{ 1 }{2x}=\frac{ 4 }{ x+2 }\] this is the equation

Answer 4

domain is restricted only function becomes undefined
dividing by 0 is undefined

set each denominator equal to zero

x+2 = 0 ---> x = -2

2x = 0 ----> x=0

The restricted x-values are -2,0

Answer 5

oh, okay. Thank you!
