Question

Make x subject of formula √x+a=b​

Answer 1

Answer:

After making x the subject of the formula, the formula is:

$x = (b-a)^2$

Step-by-step explanation:

Given formula is:

$\sqrt{x} +a = b$

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

$\sqrt{x} +a-a = b-a\\\sqrt{x} = b-a$

The subject of the formula should not be in radical form.

Taking square on both sides

$(\sqrt{x})^2 = (b-a)^2\\x = (b-a)^2$

After making x the subject of the formula, the formula is:

$x = (b-a)^2$
