Question

Combine the following expressions. Answer right pls, thanks

Answer 1

a and c  both have √x  , so they will both be in brackets multiplied by √x.

b is the only term with √y  so it will be outside of the brackets.

So the answer will be:

(a - c)√x  + b√y

We can check this by expanding the brackets:

  (a - c)√x  + b√y

= a√x  - c√x  + b√y

We can rearrange this to get the same original expression:

a√x  - c√x  + b√y

= a√x  + b√y  - c√x

Answer:

Last option: (a - c)√x  + b√y

Answer 2

Answer:

choice 3 is correct  √x(a - c) + b√y

explanation:

You simplify by looking for the common multiplier which is √x

meaning it will be

√x(a - c)  + b√y
