9a + 1
2a+5a+9a = 16a
4a2 - 9a + 5 = 4a2 - 4a -5a + 5 = 4a(a - 1) - 5(a - 1) = (4a - 5)(a - 1)
The simplified expression is -9a -9b.
There is nothing you can do to 9a + 5 without knowing the value of a.
9a + 1
a is equal to 1.
12a + 6b + 9a + 14b =(12a + 9a) + (6b + 14b) =21a + 20b
(9a + 2)(9a + 2)
2a+5a+9a = 16a
4a2 - 9a + 5 = 4a2 - 4a -5a + 5 = 4a(a - 1) - 5(a - 1) = (4a - 5)(a - 1)
a2+9a+20 = (a+4)(a+5) when factored
9a + 7b *remember to look and understand the letters!*
9a+21 3(3a+7)
The simplified expression is -9a -9b.
There is nothing you can do to 9a + 5 without knowing the value of a.
That cannot be simplified any further so it is: 9a + 45z
