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

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

Find two numbers that when added equal $- 7$ $-7$ and when multiplied equal $12$ $12$ . The numbers $- 3$ $-3$ and $- 4$ $-4$ meet the criteria.

Rewrite the expression in factored form.

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