Best ResponseYou've already chosen the best response.2well  this is the way i do it you have to consider the possibilities 10 could factor to 5 * 2 or 10 * 1 and 3 could be 1 * 3 or 1 * 3 so you have to try out different combinations so as to obtain 7 (the middle term) thats how i got 10*1 and 1 * 3  these factor to the form (ax + b)(cx + d) and adx + bcd is the middle term thats how the result is (10x  3)(x + 1) the (10 * 1) + (3 * 1) gives the 7
