Answer:
(2x - 1)^2
Step-by-step explanation:
We can reverse engineer the solution...
to complete the square, we know (2x + __)^2 will generate the 1st term 4x^2
To generate the 2nd term, we will need -1, so (2x - 1)^2....
When expanded, we will have 4x^2 - 4x + 1, which we completed the square.
Domain is the x-values put in order inside curly brackets {}
Hope this helps!

Answer:
Step-by-step explanation:
3a-2c+5ac=a
3a- a + 5ac= 2c
2a + 5ac = 2c
a ( 2 + 5c) = 2c
a = 2c / (2+5c)
