11a+9 = 4a+30 11a-4a = 30-9 7a = 21 Solution: a = 3
9a + 3b - 11a - 4b = -2a -b
It can be simplified to: 11a-11
11a-3a =8a so 8a+9=-7 8a = -16 a=-2
3
(11a + 8b)(11a - 8b)
(11a-8b)(11a+8b)
11a+9 = 4a+30 11a-4a = 30-9 7a = 21 Solution: a = 3
2a + 11a - 5a = 8a
9a + 3b - 11a - 4b = -2a -b
a(4a^2 - 11)
11a+11b
The GCF is 1.
It can be simplified to: 11a-11
11a-3a =8a so 8a+9=-7 8a = -16 a=-2
11a+7b-(3b-2a)
