20x^2+27X+9 Please explain how to do this
------------
Find two numbers whose product is 9*20 = 180
and whose sum is 27.
-----
The numbers are 15 and 12
------
Rewrite the problem:
20x^2+15x+12x+9
------
Factor the 1st two and the last two terms separately:
5x(4x+3)+3(4x+3)
Factor again to get the final factored answer:
(4x+3)(5x+3)
