(9x^5 - 2x^2 + 9x) + (6x^5 - 6x^2 + 9x)

= 9x^5 - 2x^2 + 9x + 6x^5 - 6x^2 + 9x

= 15x^5 - 8x^2 + 18x

= 9x^5 - 2x^2 + 9x + 6x^5 - 6x^2 + 9x

= 15x^5 - 8x^2 + 18x

9. Find the product.
(4x2 + 3x)(4x2 - 3x) **Weegy:** (3x-2) squared is 9x^2 - 12x + 4. (More)

The product of (4x2 + 3x)(4x2 - 3x) is: 16x^4 - 12x^3 + 12x^3 -9x^2= 16x^4 - 9x^2 = x^2*(16x^2-9).

Added 2/5/2013 5:52:33 PM

(4x^2 + 3x)(4x^2 - 3x)

= 16x^4 - 12x^3 + 12x^3 - 9x^2

= 16x^4 - 9x^2

= 16x^4 - 12x^3 + 12x^3 - 9x^2

= 16x^4 - 9x^2
