Answer:

  • See below

Step-by-step explanation:

<u>Given equation:</u>

  • 3x² + 5x + 2 = 0

<u>Factorize it in steps:</u>

  • 3x² + 5x + 2 = 0
  • 3x² + 3x + 2x + 2 = 0
  • 3x(x + 1) + 2(x + 1) = 0
  • (x + 1)(3x + 2) = 0

<u>The roots are:</u>

  • x + 1 = 0 ⇒ x = - 1
  • 3x + 2 = 0 ⇒ 3x = - 2 ⇒ x = - 2/3
