Question

The following polynomial can be factored using the techniques of this lesson x^2-18

Answer 1

The answer is false.

Explanation:

Answer 2

`(x+3√(2))(x-3√(2))`

Explanation:

The given expression is
`x^2-18`.

The technique that can be used to factor this polynomial is the difference of two squares.

We rewrite the two expressions as;

`x^2-(√(18))^2`

Recall that;

`a^2-b^2=(a+b)(a-b)`

`x^2-(√(18))^2=(x+√(18))(x-√(18))`

`x^2-(√(18))^2=(x+3√(2))(x-3√(2))`
