The given terms can be simplified to: a -b
5a times 3a minus 8a = (5*3)*a2 - 8a = 15a2 - 8a
2a + 11a - 5a = 8a
It is: x-1+4+7x-3 = 8x simplified
-8i
The given terms can be simplified to: a -b
It is an algebraic expression that can be simplified to: 4.5a-2.5
8a-a-a = 6a
9a-a = 19+7a 8a = 19+7a 8a - 7a = 19 + 7a - 7a 1a = 19 a = 19
1a
The simplified expression is -9a -9b.
That cannot be simplified any further so it is: 9a + 45z
12
a^2 + 8a + 15
5a times 3a minus 8a = (5*3)*a2 - 8a = 15a2 - 8a
2a-5
