Answer:
(x-4)(x-3)
Step-by-step explanation:
multiply 1 and 12= 12
find two numbers that multiply to get twelve AND add together to get -7(the middle number)
the two numbers are -3 and -4 (they add up to get -7 AND multiply together to get 12)
plug in these numbers for -7x
x(x-3)-4(x-3)
the bolded is the first binomial and the second binomial is in the parenthesis.
(x-4)(x-3)
