Question

2a+9b-2A-b

Answer 1

Combine the like terms.

Answer 2

(2a,-2a) (9b,-b)

Answer 3

Yes, exactly. What do you get then?

Answer 4

I am having trouble simplifying

Answer 5

Just operate on the coefficient.

\( \color{Black}{\Rightarrow 2a - 2a = (2 - 2)a = 0a = 0 = \textbf{ZILCH! :D} }\)

Answer 6

and the other one?

Answer 7

9b-(-b)=

Answer 8

9b?

Answer 9

Well actually that's \(9b - b\).

Answer 10

so the simplified equation is 9+0=9

Answer 11

\( \color{Black}{\Rightarrow 9b - b = 9b - 1b }\)

Apply the same trick ;D

Answer 12

9b-0a

Answer 13

8b-0a

Answer 14

Yes, but 0a = 0 = ZILCH

Answer 15

or 8b-a

Answer 16

So you need not write 0. That leaves 8b.

Answer 17

oh ok i get it

Answer 18

hmm cool
