Answer:
Remember the distributive property of the multiplication, this means that:
A*(B + C) = A*B + A*C
And the commutative property of the addition is:
A + B = C
then:
B + A = C
We can use this property in our expression:
a√x + b√y -c√x
We can use the commutative property of the addition to rewrite this as:
a√x - c√x + b√y
(a√x - c√x) + b√y
Now we can use the distributive property in the left term:
(a - c)√x + b√y
Then we got:
a√x + b√y -c√x = (a - c)√x + b√y
