Multiple choice: Please select the best answer and click \"submit\". What are the zeros of the polynomial function F(x) = x^2 - 5x - 6? X = 2 and x = 3 X = -1 and x = 6 X = -6 and x = 1 X = -3 and x = -2

Solution

F(x) = x^2-5x-6
     = x^2-6x+x-6
   = x(x-6)+1(x-6)
   =(x-6)(x+1)
  
put F(x) = 0 to find zeroes
(x-6)(x+1) = 0
x=6 and x=-1

Answer: B
