Step-by-step explanation:
2x^2-5x+7=0
2x^2-7x+2x+7=0

2x² - 5x + 7 = 0
2x² + 7x - 2x + 7 = 0
x ( 2x + 7 ) -1 ( 2x + 7 ) = 0
( x - 1 ) ( 2x + 7 )
So x can be :
1. x - 1 = 0
x = I
2. 2x + 7 = 0
2x = -7
x = -7/2

2x² + 7x - 2x + 7 = 0
x ( 2x + 7 ) -1 ( 2x + 7 ) = 0
( x - 1 ) ( 2x + 7 )
So x can be :
1. x - 1 = 0
x = I
2. 2x + 7 = 0
2x = -7
x = -7/2
