Question

the quotient of negative eight and the sum of a number and three

Answer 1

For this case, the first thing we must do is define a variable.
 We have then:
 x: real number
 Now we write the expression:
 -8 / (x + 3)
 The number x can be all real different from minus three.
 Answer:
 -8 / (x + 3)
 With x different from -3.
