2a+5a+9a = 16a

(9a + 2)(9a + 2)

a2+9a+20 = (a+4)(a+5) when factored

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

-14 + 9a = 389a = 52a = 52/9 or 5.78

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

9a+21 3(3a+7)

9a + 3b - 11a - 4b = -2a -b

The simplified expression is -9a -9b.

That cannot be simplified any further so it is: 9a + 45z

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

9a + 1

Collect like terms: 9a -7a = 9 - 15, ie 2a = -6, so a = -3

a= -0.8

12

That factors to (x + 5)(x + 4)

a is equal to 1.

a= -4

3(3a+b)

It is 3a(a+3) when factored

a(a^2 - 9a + 3)

10a + 3a - 4a = 9a

It is: 12a+2 when simplified

3a squared plus nine = 19a. 3a to the second power = 9a plus 9 = 19a.

4a - 2.1 = 9a + 5.4 4a - 9a = 5.4 +2.1 -5a = 7.5 -a = 1.5 a = -1.5
