Express f(x) =3\x²- 1 in partial fraction​
BARSIC [14]

3/(<em>x</em> ² - 1) = 3/((<em>x</em> - 1) (<em>x</em> + 1)) = <em>a</em>/(<em>x</em> - 1) + <em>b</em>/(<em>x</em> + 1)

==>   3 = <em>a</em> (<em>x</em> + 1) + <em>b</em> (<em>x</em> - 1)

==>   3 = (<em>a</em> + <em>b</em>) <em>x</em> + <em>a</em> - <em>b</em>

==>   <em>a</em> + <em>b</em> = 3 and <em>a</em> - <em>b</em> = 0

==>   <em>a</em> = <em>b</em>

==>   <em>a</em> + <em>b</em> = 2<em>a</em> = 3   ==>   <em>a</em> = 2/3 and <em>b</em> = 2/3

So you have

3/(<em>x</em> ² - 1) = 2/(3(<em>x</em> - 1)) + 2/(3(<em>x</em> + 1))

Answer:
