Answer 1

Răspuns:

Explicație pas cu pas:

x^2 + 3x + 2 =

x^2 + x + 2x + 2 =

x (x + 1) + 2 (x + 1) =

(x + 1) (x + 2)

Answer 2

${x}^{2} + 3x + 2 = {x}^{2} + x + 2x + 2 = x( \frac{ {x}^{2} }{x} + \frac{x}{x}) + 2( \frac{2x}{2} + \frac{2}{2}) = x( {x}^{2 - 1} + 1) + 2(x + 1) = x(x + 1) + 2(x + 1) = (x + 1)( \frac{x(x + 1)}{x + 1} + \frac{2(x + 1)}{x + 1}) = (x + 1)(x + 2)$
