Answer? - 1/3a+ 1
+
1-a? /2a+ 1
6.x? -2xy+y? /x? -Really? , where x= 1 10 and y= 10. (Simplify first, then evaluate)
7. Known (x- 1)(x-2)/3x-4
=
X- 1 a
+
X-2 b, reality number a, B.
8.( 1-x)? /2x;
1.-7ab/c
2.(x-4)/2
3.-a^2*b/2*x^2*b
4.2*x/(x^2- 1)
5.2*a/(a^2- 1)
6.(x+y)*(x-y)/(x-y)^2=(x+y)/(x-y)= 1.2
7.(3x-4)/(x- 1)(x-2)= 1/(x- 1)+2/(x-2)
therefore
A= 1
B=2
8.2/( 1-x)( 1/x- 1)
