Answer:
After making x the subject of the formula, the formula is:
[tex]x = (b-a)^2[/tex]
Step-by-step explanation:
Given formula is:
[tex]\sqrt{x} +a = b[/tex]
Making a variable subject of a formula or equation means that the variable has to be isolated in the equation to write it in terms of other variables and constants.
So,
In the given formula,
Subtracting a from both sides
[tex]\sqrt{x} +a-a = b-a\\\sqrt{x} = b-a[/tex]
The subject of the formula should not be in radical form.
Taking square on both sides
[tex](\sqrt{x})^2 = (b-a)^2\\x = (b-a)^2[/tex]
After making x the subject of the formula, the formula is:
[tex]x = (b-a)^2[/tex]
