Answer :
x = (3 + √19)/5 , (3 - √19)/5
Solution :
• Given quadratic equation : 5x²-6x-2 = 0
• To find : Roots by completing squaring method
We have ;
=> 5x² - 6x - 2 = 0
=> x² - (6/5)x - 2/5 = 0
=> x² - (6/5)x + (3/5)² - (3/5)² - 2/5 = 0
=> (x - 3/5)² - 9/25 - 2/5 = 0
=> (x - 3/5)² = 9/25 + 2/5
=> (x - 3/5)² = (9 + 10)/25
=> (x - 3/5)² = 19/25
=> x - 3/5 = √(19/25)
=> x - 3/5 = ± √19/5
=> x = 3/5 ± √19/5
=> x = (3 + √19)/5 , (3 - √19)/5
Hence ,
x = (3 + √19)/5 , (3 - √19)/5
