Question

find the rational number when 2x⁴ - x³ + 2x² + x - 1 ÷ x - 2​

Answer 1

Step-by-step explanation:

First of all, you must rewrite the integrand in the form

x + 1 + [ 4x /(x +1)(x - 1)^2 ].

Then use the method of partial fractions to finish the integrations.

ie. write as A/(x + 1) + B /(x - 1) + C/(x - 1)^2 etc.

Answer:

33 or 33/1 is the correct answer
