Solution :
2x² - 9x - 5 = 0
=> 2x² - 10x + x - 5 = 0
=> 2x( x - 5 ) + 1( x - 5 ) = 0
=> ( x - 5 )( 2x + 1 ) = 0
=> x - 5 = 0 or 2x + 1 = 0
Therefore ,
x = 5 or x = -1/2

2x² - 9x - 5 = 0
=> 2x² - 10x + x - 5 = 0
=> 2x( x - 5 ) + 1( x - 5 ) = 0
=> ( x - 5 )( 2x + 1 ) = 0
=> x - 5 = 0 or 2x + 1 = 0
Therefore ,
x = 5 or x = -1/2

2x square - 9x - 5 = 0
2x square - (10-1)x - 5 = 0
2x square - 10x - x - 5 = 0
2x(x-5) - 1(x-5) = 0
(2x-1)(x-5) = 0
either (2x-1) = 0 or (x-5) = 0
therefore, either x = 1/2 or x = 5
2x square - (10-1)x - 5 = 0
2x square - 10x - x - 5 = 0
2x(x-5) - 1(x-5) = 0
(2x-1)(x-5) = 0
either (2x-1) = 0 or (x-5) = 0
therefore, either x = 1/2 or x = 5
