Step-by-step explanation:

[tex]a = \sqrt{b - a} [/tex]

firstly square

[tex] \sqrt{b- a} [/tex]

to get a-b on it's own

it's now

[tex]a = b - a[/tex]

now plus the a to cancel out the minus a to get

[tex]a {}^{2} = b[/tex]

which can also be written as

[tex]b = a {}^{2} [/tex]

dont know if that makes sense as I'm not the best at trying to explain
