Question 15:
 We find the zero for:
 x = -3
 The quadratic equation of factored form is:
 p (x) = (x + 3) * (x + 3)

 Question 16: 
 We find the zero for:
 x = -2
 x = 3
 The quadratic equation of factored form is:
 p (x) = - (x + 2) * (x-3)
 Question 17:
 
We find the zero for:
 x = -2
 x = 0.5
 The quadratic equation of factored form is:
 p (x) = (x + 2) * (2x-1)
