Question

(3x^2-11)(3x^2+11)
multiply the following polynomials

Answer 1

[ Answer ]

`\boxed{9x^(4) \ - \ 121}`

[ Explanation ]

Multiply The Following Polynomials

(
`3x^(2)` - 11) * (
`3x^(2)` + 11)

=========================

Apply Difference Of Two Squares Formula

`(3x^(2))^(2) \ - \ 11^(2)`

Simplify

`(3x^(2))^{2 \ - \ 11^(2)`:
`9x^(4) \ - \ 121`

=
`9x^(4) \ - \ 121`

`\boxed{[ \ Eclipsed \ ]}`

Answer 2

9x^2 - 121

Explanation:

Sum and difference: (a - b)(a + b) = a^2 - b^2

In this case:

(3x^2-11)(3x^2+11)

= (3x)^2 - 11^2

= 9x^2 - 121
