I need help with this question. Please explain thoroughly and Please write clear, readable answers. Thank you. Use Partial Fraction Decomposition to evaluate: 5x2+8x+20 fdx x(x2+2x+5) After you decompose, you will get 2 integrals. The first is very easy. For the second you will need to use substitution 2 times. For the first substitution, rewrite the denominator x2+2x+5 as (x+1)2+4- and use substitution: u.=x+1. To integrate the resulting integral, split the denominator and obtain two integrals. For one of the resulting integrals, you will need to use another substitution
