Answer 1

Step-by-step explanation:

⇒ (x² + x - 3) + (4x - 1) + (2x² + 3x)

= x² + x - 3 + 4x - 1 + 2x² + 3x

= 3x² + 5x + 3x - 4

= 3x² + 8x - 4

By Middle Term Splitting

= 3x² + 6x + 2x - 4

= 3x(x + 2) - 2(x + 2)

= (x+2)(3x - 2)

Answer 2

Step-by-step explanation:

$= ( {x}^{2} + x + 3) + (4x - 1) + ( {2x}^{2} + 3x) \\ = {x}^{2} + x- 3 + 4x - 1 + {2x}^{2} + 3x \\ {3x}^{2} + 5x + 3x - 4 \\ = {3x}^{2} + 8x - 4 \\ middle \: term \: spilliting \\ = {3x}^{2} + 6x + 2x - 4 \\ = 3x(x + 2) - 2(x - 2) \\ = (x + 2)(3x - 2) \\ \\ please \: mark \: me \: as \: brainlist$
