(3x^2)^3 / x^15

= 27x^6/x^15

= 27/x^9

= 27x^6/x^15

= 27/x^9

Perform the indicated operations. Write the resulting polynomial in standard form.
(4x^7 + 8x^6 + 12) - (7x^7 - 17x^6 - 11) **Weegy:** answer: x= -5. **User:** Find the product.
(9x^3 + 2)(x^2 - 7) **Weegy:** (x - 2)(x + 7) = x^2 + 5x -14 **User:** Factor by grouping. Assume any variable exponents represent whole numbers.
x^3 - 4x^2 + 5x - 20 **Weegy:** The answer is (x? - 5)(x + 4). **User:** Factor the difference of two squares.
25x^2 - 4 **User:** Factor completely, or state that the polynomial is prime.

(4x^7 + 8x^6 + 12) - (7x^7 - 17x^6 - 11)

= 4x^7 + 8x^6 + 12 - 7x^7 + 17x^6 + 11

= -3x^7 + 25x^6 + 23

= 4x^7 + 8x^6 + 12 - 7x^7 + 17x^6 + 11

= -3x^7 + 25x^6 + 23

x^3 - 4x^2 + 5x - 20

= x^2(x - 4) + 5(x - 4)

= (x - 4)(x^2 + 5)

= x^2(x - 4) + 5(x - 4)

= (x - 4)(x^2 + 5)
