(x-4) (x-3) The numbers must add to equal the middle # and multiply to equal the last#

factors of 12 are 1, 2, 3, 4, 6, 12
which two factors when u add do u get 7 and their product 12? its 3 and 4.
now, the 7 in the equation is negative and the 12 (product of the two factors) is positive.
therefore, both the factors must be negative. (negative x negative= positive) and (negative+negative=negative)
so u get (x-4)(x-3)

(x - 4)(x - 3)
-
(x - 4)*(x - 3)

x² - 7x + 12 = (x - 4)(x - 3)
