Answer 1

Answer:

answer is 6

Step-by-step explanation:

=1×1-7×1+12

=1-7+12

=-6+12

=6

Answer 2

Step-by-step explanation:

${x}^{2} - 7x + 12 \\ = {x}^{2} - 4x - 3x + 12 \\ = x(x - 4) - 3(x - 4) \\ = (x - 4)(x - 3)$

If $x = 1$

Then,

$(x - 4)(x - 3) \\ = (1 - 4)(1 - 3) \\ = ( - 3) \times ( - 2) \\ = 6$
