Question

please solve the 6th question

Answer 1

Answer:

6 (3rd) x = 2 and x = 1/2

Step-by-step explanation:

6 (3rd): to solve 2/x² - 5/x + 2 = 0

multiply both sides by x²

2 - 5x + 2x² = 0

=> 2x² - 5x + 2 = 0

a = 2 , b = -5, c = 2

x = [-b ± √(b² - 4ac)] / 2a

x = -(-5) ± √ {(-5)² - 4(2)(2) }

x = [5 ± √ (25 - 16)] / 2*2

x = [5 ± √ (9)]/4

x = (5 ± 3) / 4

x = (5+3)/4 => 8/4 => 2

x = (5 - 3)/4 => 2/4 => 1/2
