Answer 2

Answer:

What 1/2x-5+5/2x-1=2 do by using quadratic formula?

OnePlus 7T.

1/(2x - 5) + 5/(2x - 1) = 2 => multiply both sides by LCD:

2x - 1 + 5(2x - 5) = 2(2x - 5)(2x - 1)

2x - 1 + 10x - 25 = 2(4x^2 - 12x + 5)

12x - 26 = 8x^2 - 24x + 10

8x^2 - 36x + 36 = 0

2x^2 - 9x + 9 = 0

a = 2, b = -9, c = 9

x = [-b ± √(b^2 - 4ac)]/(2a)

x = [9 ± √(81 - 72)]/4

x = (9 ± √9)/4

x = ( 9 ± 3)/4

x = 3/2 or x = 3
