Question 1068790
a factor of x^2-5x^2-8x+12 is
c)x-1 because f(1) = 0
---------------------------- 
which of the following binomials is a factor of 8x^3-4x^2-2x+1
a) x-1 ; no because f(1) is not zero
b) X+2 : no because f(-2) is not zero
c) 2x+1 : yes because f(-1/2) is zero
d) 5x+1 : no because f(-1/5) is not zero
------------------------------------------------
which of the following represents a family of cubic polynomials with zeros -4,2 and 6

Ans:: c) y=k(x+4)(x-2)(x-6)
