Question

Solve y=x^2+23 for x

Answer 1

x = +/- (square root) y-23

Explanation:

A P E X

Answer 2

For this case we must clear x from the given equation:

`y = x ^ 2 + 23`

We passed 23 subtracting the other side of equality:

`y-23 = x ^ 2`

By definition,
`a ^ 2 = b`is written as
`a = +/-√(b)`

So, we have:

`x = + / -\sqrt{(y-23)`

So, the solution of
`y = x ^ 2 + 23` for x is:

`x = + / -\sqrt{(y-23)`

Answer:

`x = + / -\sqrt{(y-23)`

`x1=+\sqrt{(y-23)`

`x2=-\sqrt{(y-23)`
