Question

x^2-mx+1=0 then what is the value of x+1/x​

Answer 1

Required Answer:-

Given:

• x² - mx + 1 = 0

To find:

• The value of x + 1/x

Solution:

We have,

➡ x² - mx + 1 = 0

Dividing both sides by x, we get,

➡ (x² - mx + 1)/x = 0/x

➡ x²/x - mx/x + 1/x = 0

➡ x - m + 1/x = 0

Move m to right,

➡ x + 1/x = m

★ Hence, the value of x + 1/x is m.

Answer:

• x + 1/x = m.
