while using ac test determine if the following trinomial can be factored. if so how do you find the value of m and n
3x^2+11x-4
a=3 ; b=11; c=-4
ac=-12
b=11
--------------
Find two numbers whose product is -12 and whose sum is 11
The numbers are -12 and 1.
Rewrite the problem as:
3x^2-12x+x-4
Factor the 1st two and then the last two terms separately to get:
=3x(x-4)+(x-4)
Factor again:
=(x-4)(3x+1)
