Answer 1

$answer$

The value of n is

(i) 2.75

(ii) 0.54

Given equation is :

(2n-5) × (5n-4) = 5

10n² -8n -25n +20 = 5

10n²-33n +15 = 0

Here, a= 10, b= -33, c= 15

Now,

D= b²-4ac

= (-33)² - 4(10 * 15)

= 1089-600

= 489

Roots:

\frac{-b+\sqrt{D} }{2a} and

Upon putting the values and solving we get,

n= 2.75 and 0.54.
