x^2 - 4x - 3x + 12

= x^2 -7x +12

middle term=     -7x

Answer:

The middle term of the equation is  (x - 4)(x - 3) is -7x .

Step-by-step explanation:

As given the expression in the question be as follow .

= (x - 4)(x - 3)

First open the bracket and simplify the above terms .

=  x × x - x × 3 - 4 × x -4 × -3

= x² -3x -4x + 12

= x² -7x + 12

Therefore the middle term of the equation is  (x - 4)(x - 3) is -7x .
