Answer:

It is not permitted the denominator to be zero as we can't divide by zero.

Non- permissible values are:

a)  

  • ab² = 0
  • a = 0, b = 0

b)  

  • 3n + 1 = 0
  • n = -1/3

c)  

  • 4 - a = 0
  • a = 4

d)  

  • x² - x - 12 = 0  
  • (x - 4)(x + 3) = 0
  • x = 4 or x = -3

e)  

  • 10x³ - 92x² + 18x = 0
  • 2x(5x² - 46x + 9) = 0
  • x(5x - 1)(x - 9) = 0
  • x = 0, x = 1/5, x = 9
