Hi,
if x=-2/3 and x=1/4 are the roots of the quadratic equation ax^2+bx+c=0,
then which of the following could represent the two factors of ax^2+bx+c? 
 (3x+2)(4x-1) = 0   | yes one could do the substituting of the roots.
Many will recognize from factoring and finding solutions, in general...that
IF 
 (3x+2)(4x-1) = 0 
THEN
  x = -2/3   and x = 1/4
