1) Subtract:

g-2 / 6 (g - 2 over 6) - g+3 / 9 (g+3 over 9)

Ag-12/18
B-2/18
C-g-5/18
Dg-5/18


2) Divide and simplify:


(a+5)(a-2) / a^2 - a ÷ 3(a+5) / (a-1)(a-2)

Aa+5 / a-2
B(a-2)² / 3
C(a-2)² / 3a
D3(a+5)² / a(a-1)²



3) Factor completely:


81x4 – 1


A.(9x2 + 1)(3x + 1)(3x – 1)

B.(3x + 1)2(3x – 1)2

C.(9x2 + 1)(9x2 – 1)

D.(3x + 1)(3x – 1)

1) a
2) c
3) c
Details can be explained, it is easier to work backwards from a solution through the problem, though. I hope this helps at all.
