The partial fraction of

\frac{{3{x^3} - 8{x^2} + 10}}{{{{\left( {x - 1} \right)}^4}}}

View answer and explanation

Correct option: B

\frac{3}{{\left( {x - 1} \right)}} + \frac{1}{{{{\left( {x - 1} \right)}^2}}} - \frac{7}{{{{\left( {x - 1} \right)}^3}}} + \frac{5}{{{{\left( {x - 1} \right)}^4}}}

Option B (

\frac{3}{{\left( {x - 1} \right)}} + \frac{1}{{{{\left( {x - 1} \right)}^2}}} - \frac{7}{{{{\left( {x - 1} \right)}^3}}} + \frac{5}{{{{\left( {x - 1} \right)}^4}}}

) is correct because it represents the correct partial fraction decomposition of the given expression.

\frac{1}{{\left( {1 + x} \right)\left( {1 + {x^2}} \right)}} = \frac{A}{{1 + x}} + \frac{{f\left( x \right)}}{{1 + {x^2}}}

f\left( x \right)

\frac{{{x^3}}}{{\left( {2x - 1} \right)\left( {x + 2} \right)\left( {x - 3} \right)}} = A + \frac{B}{{2x - 1}} + \frac{C}{{x + 2}} + \frac{D}{{x - 3}}

A

\frac{{{x^2} + x + 1}}{{{x^2} + 2x + 1}} = A + \frac{B}{{x + 1}} + \frac{C}{{{{\left( {x + 1} \right)}^2}}}
