1) subtract:
g-2 / 6 (g - 2 over 6) - g+3 / 9 (g+3 over 9)
a. g-12/18
b. -2/18
c. -g-5/18
d. g-5/18
2) divide and simplify:
(a+5)(a-2) / a^2 - a ÷ 3(a+5) / (a-1)(a-2)
a. a+5 / a-2
b. (a-2)² / 3
c. (a-2)² / 3a
d. 3(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)
