Question

2(x^2+1) =5x

find x+1/x

plz explain each step with reason

Answer 1

Answer:

3/2

and

3

Step-by-step explanation:

2x²+2 = 5x

2x²- 5x + 2 = 0

2x²-4x-x + 2 = 0

by solving we get

x = 2 or x = 1/2

by putting x value one by one we get two values of x+1/x

i.e. 3/2 and 3

Answer 2

answer:

explanation:

• As x=2 or 1/2
• x+1/x
• 2+1/2=5/2

or

• 1/2+1/1/2=5/2

• therefore x+1/x is 5/2
