Question

$2x ^{2} - 3x - k + 2 = 0 \: \: \: \: \: \: k =$
​

Answer 1

Question :-

=> 2x² - 3x - k + 2 = 0

Answer :-

=> 2x² - 3x - k + 2 = 0

=> 2x² - 3x + 2 = 0 + k

=> 2x² - ( 4 - 1 )x + 2 = k

=> 2x² - 4x + 1x + 2 = k

=> 2x ( x - 2 ) -1 ( x - 2 ) = k

•°• k = ( x - 2 ) or ( 2x - 1 )

Let , k = ( x - 2 )

=> x - 2 = 0

=> x = 0 + 2

=> x = 2 ✓

Again let , k = ( 2x - 1 )

=> 2x - 1 = 0

=> 2x = 0 + 1

=> x = 1/2 ×

we know that , value of x can not be in decimal , negative or fraction form

•°• k = ( x - 2 )
