Question

Please show how to solve this:
If √x - a = b, then x = ?

(-a is not under the root sign)

Answer 1

Easy problem, but I just forgot how to solve it

Answer 2

\[\large \sqrt x-a=b\]
So let's start by adding \(\large a\) to each side. What do you get? :O

Answer 3

√x = a + b

Answer 4

k looks good so far c:

Answer 5

does x = (a + b)^2

Answer 6

Yes! Good! :)
That might be your final answer, depending on whether or not your teacher wants you to expand out the binomial containing a and b.

Answer 7

okay, thanks so much for your help :)
