Question

if x is equal to 4 minus root 15 find the value of x + 1 by X

Answer 1

Step-by-step explanation:

x=4-√2

x=4-1.4

x=2.6

x+1=3.6

Answer 2

Answer:

in here

x= 4-√15

x+1/x = 4-√15 + 1/4-√15

now rationalize the denominator of the 2nd term that is 1/4-√15

1/4-√15×4+√15/4+√15 (a²-b²)

we get 4+√15

x+1/x= 4-√15+4+√15

=8
