Answer:

x = -2/5

x = 1

Step-by-step explanation:

5x² - 3x - 2 = 0

(5x + 2)(x - 1) = 0

⇒ 5x + 2 = 0

⇒ 5x = -2

⇒ x = -2/5

⇒ x - 1 = 0

⇒ x = 1

Answer:

[tex]5 {x}^{2} - 3x - 2 = 0 \\ 5 {x}^{2} - 5x + 2x - 2 = 0 \\ 5x(x - 1) + 2(x - 1) = 0 \\ (x - 1)(5x + 2) = 0 \\ x = 1 \: and \: \frac{( - 2)}{5} [/tex]

  • x = 1 and (-2/5) is the right answer.
