Answer 1

Answer:

$= > {x}^{2} - 2x - 3 \\ \\ = > {x}^{2} - 3x + x - 3 \\ \\ = > x(x - 3) + 1(x - 3) \\ \\ = > (x - 3)(x + 1) \\ \\ to \: find \: x \\ \\ = > (x - 3)(x + 1) = 0 \\ \\ = > x - 3 = 0 \: \: \: \: \: \: \: \: x + 1 = 0 \\ \\ = > x = 3 \: \: \: \: \: \: \: \: x = - 1$

Answer 2

x² - 2x - 3.

x² - (3-1)x - 3.

x² - 3x + x - 3.

x(x-3) + 1(x-3).

(x+1)(x-3)

x=-1,

x= 3.
