Answer:
a=
b =
Step-by-step explanation:
- By equating coefficients on both sides of respective terms.
Given,
=
+ 
<u>Now take </u><u>lcm</u><u> on right hand side </u>
=
By equating coefficients of respective terms
x-4 = a(x-2)+b(x+9)
a+b=1 -----1 ; 9b-2a=-4 -----2
Substitute b=1-a in 2
9(1-a)-2a=-4
11a=9+4=13
a=
As b=1-a=1-
=
