Combine the following expressions.
Answer right pls, thanks
2 answers:
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:
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
