Question

if x+1/x =16 find the value of 85x/x^2 +x+1​

Answer 1

Answer:

we have an equation as

x+1/x=−2x+1/x=−2

take the -2 to the left side, equation can be written as

x+1/x+2=0x+1/x+2=0

((x)1/2+(1/x)1/2)2=0((x)1/2+(1/x)1/2)2=0

(x)1/2+(1/x)1/2=0(x)1/2+(1/x)1/2=0

which will again be written as

x+1=0x+1=0

so we got x=−1x=−1

now, we’ll put the of xx in given question!

x(37)+1/x(100)=(−1)(37)+(1/(−1))(100)=−1+1=0.x(37)+1/x(100)=(−1)(37)+(1/(−1))(100)=−1+1=0.

this is great method to inspect!
