Answer:

Option C

Step-by-step explanation:

you cancel the whole parentheses.

So you know, x+6 can't equal to 0.

that's why there is a choice that is all real numbers but not -6.

Answer:

A. All real numbers

Step-by-step explanation:

Given

  • (x - 2)(x + 6)/7(x + 6) = (x - 2)/7

On cross multiplying,

  • (x - 2)(x + 6)(7) = (x - 2)(x + 6)(7)
  • LHS = RHS
  • This means on applying any value for x, both sides will be equal
  • Hence, the correct option is A
