Answer:

d.  x = -3

Step-by-step explanation:

<u />\sqrt{(x + 3)}÷ (x+8)(x-2) = 0

f(x) / g(x) = 0

Variable x cannot be equal to any of the values −8,2 since division by zero is not defined. Multiply both sides of the equation by (x−2)(x+8).

<u />\sqrt{(x + 3)} = 0 ------ square both sides

x + 3 = 0

solve for x:

x = -3
