Question

If x=√5+2 then x-1/x is equal to

Answer 1

Answer:

$x = \sqrt{5} + 2$

$\sqrt{5} + 2 - 1 \div \sqrt{5} + 2$

$\frac{ \sqrt{5} + 1}{ \sqrt{5} + 2 }$

$\frac{( \sqrt{5} + 1)( \sqrt{5} - 1)}{ \sqrt{5}^{2} - 4 }$

$= \frac{4}{3}$

Answer 2

Answer:

6

Step-by-step explanation:

x=√5+2

to find  x-1/x

substituting value of x with √5+2

=√5+2-(1/√5+2)

=(5+4+4√5-1)÷√5+2

=(8+4√5)÷√5+2

=√5 and √5 gets cancelled

=(8+4)÷2

=12÷2

=6
