Answer 1

Answer:

${x}^{2} −7x+12$

Step-by-step explanation:

$(x−3)(x−4)$

$x(x−4)−3(x−4)$

$x \times x+x(−4)−3x−3(−4)$

${x}^{2} −4x−3x+12$

${x}^{2} −7x+12$

Answer 2

Answer:

x

${x}^{2} - 7x + 12$

Step-by-step explanation:

$(x - 3)(x - 4)$

$x( x - 4) - 3(x - 4)$

${x}^{2} - 4x - 3x + 12$

${x}^{2} - 7x + 12$
