Question

@ The sum of a nber it's reciprocal is 17/4. find the number
​

Answer 1

Answer:

x + 1/x = 17/4

or, x²+1= 17x/4

or, 4x² + 4 = 17x

or, 4x² - 17x + 4 = 0

or, 4x²-16x - x + 4 = 0

or, 4x( x - 4) - 1( x - 4) = 0

either 4x - 1 = 0

then 4x = 1

or, x = 1/4

or, x - 4 = 0

or, x = 4

x = 1/4 or 4
