Use the ac test to determine if the following trinomial can be factored. Find the values of m and n if the trinomial can be factored.
x^2 - 3x + 7
AC=1*7=7....WE HAVE TO SPLIT IT IN TO 2 FACTORS WHOSE SUM IS -3
THERE ARE NO SUCH FACTORS.
SINCE THE SMAQLLEST SUM IS -SQRT(7)-SQRT(7)..WHICH IS LESS THAN -3
HENCE THE TRINOMIAL CANNOT BE FACTORED
