8) a/b +b/a=-1
a²+b^2=-ab
a²+b^2+ab=0
multiply by a-b to both sides
(a-b)(a²+b²+ab)=0
a³-b³=0
9)2x +40+3x=180
5x=140
X=28
10) mean=a
median=b
mode=c
a/b=2/3
b=3a/2
now c=3b-2a
c=9a/2 -2a
multiply by 2
2c=9a-4a
2c=5a
c/a=5/2=mode/mean
a²+b^2=-ab
a²+b^2+ab=0
multiply by a-b to both sides
(a-b)(a²+b²+ab)=0
a³-b³=0
