Answer 1

(D)
`p^(2) -9p+18`

Explanation:

Assuming that the equation
`x^(2) -2` = p, we can convert the equation into this.

`p^(2) +18=9p`

We can convert
`9x^(2) -18` into 9p because
`x^(2) -2` × 9 =
`9x^(2) -18`

Now we simplify this equation.

We can subtract 9p from both sides of the equation.

`p^(2) +18-9p = 0`

Re-ordering the equation gets us:

`p^(2) -9p+18`

So, (D)
`p^(2) -9p+18` is equivalent to the original expression of
`(x^(2) -2)^(2) + 18 = 9x^(2) -18`
