9a verbal expression

-a^2- 9a - 18 = 0 -(a^2 + 9a + 18) = 0 -(a + 6)(a + 3) = 0

9a + 7b *remember to look and understand the letters!*

9a +8 -2a -3 -5a = 2a +5

It is: -7a when simplified

Related questions

9a4-b2=36a-2b=2(18-b) But if you meant 9a^4-b^2 it is not possible to factor

9a-99 = -90

It is: 9a-a-a = 7a

It is the same as: 9a -4a = 5a

9a - 8a = a

If: 9a = 18b Then: a = 2b

9a squared = 81a^2

9a verbal expression

9a+21 3(3a+7)

There is nothing you can do to 9a + 5 without knowing the value of a.

The simplified expression is -9a -9b.

12a + 6b + 9a + 14b =(12a + 9a) + (6b + 14b) =21a + 20b
