Question 1149076
<br>
(1) The constant term is negative, so the signs in the two factors are opposite (one +, one -):  (ax+b)(cx-d)<br>
(2) The product ac is 3.  There are only 2 possibilities -- 3 and 1, or 1 and 3.<br>
(3) The product bd is 2.  There are only 2 possibilities -- 2 and 1, or 1 and 2.<br>
That makes 2*2 = 4 possibilities for the correct factorization.  Try them all and see which gives the correct middle term.<br>
{{{(3x+2)(x-1)}}}?
{{{(3x+1)(x-2)}}}?
{{{(x+2)(3x-1)}}}?
{{{(x+1)(3x-2)}}}?<br>
