Multiple Choice

A logistics analyst at Nexus Shipping is merging two performance formulas represented by the expressions 7x+12x+3\frac{7x+12}{x+3} and x2x+3\frac{x^2}{x+3}. To simplify the combined total, the analyst merges the numerators into the trinomial x2+7x+12x^2 + 7x + 12 and then factors it into (x+3)(x+4)(x+3)(x+4). According to the standard rules for factoring trinomials, which mathematical relationship explains why the numbers 3 and 4 are chosen for these factors?
