Answer 1

Answer:

The Question might be WRONG!!!

Step-by-step explanation:

Let x + 1/x = A --------------------------------1

Square both the sides

x² + 1/x² +2 =  A

x² + 1/x² = A - 2 -----------------------------2

Multiply 1 and 2 eqn.s

(x + 1/x) × (x² + 1/x²) = (A) × (A - 2)

x³ + 1/x + x + 1/x³ = A² - 2A

x³ + 1/x³ + A = A² - 2A (From 1,   x + 1/x = A)

x³ + 1/x³ = A² - 3A ---------------------------------3

Put the values in given question

(A² - 3A) - 5(A - 2) + A

A² - 3A - 5A + 10A + A =

A² + 3A
