1. (i) x2 + 3x + 2​

Answer 1

Step-by-step explanation:

${ {x}^{} }^{2} + 3 {}x + 2$

${x}^{2} + (2 + 1)x + 2$

${x}^{2} + 2x + x + 2$

$x(x + 2) + 1(x + 2)$

$(x + 2)(x + 1)$

Answer 2

Answer:

$(x + 1) \: \: (x + 2)$

Step-by-step explanation:

${x}^{2} + 3x + 2$

${x}^{2} + 2x + x + 2$

$x(x + 2) \: \: \: + 1(x + 2)$

$(x + 1) \: (x + 2)$
