User: Perform the indicated operations. Write the resulting polynomial in standard form. (9x^4 + 2x^3 + 6x^2 - 6) - (5x^4 + 7x^3 + 3x^2 + 3)

Weegy: (9x^4 + 2x^3 + 6x^2 - 6) - (5x^4 + 7x^3 + 3x^2 + 3) the answer is 4x^4-5x^3+3x^2-9

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. 98y^4 - 8y^2 (More)

(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

(9x^3 + 2)(x^2 - 7) = 9x^5 - 63x^3 + 2x^2 - 14
Confirmed by yumdrea [7/4/2014 3:52:15 PM]
x^3 - 4x^2 + 5x - 20
= x^2(x - 4) + 5(x - 4)
= (x - 4)(x^2 + 5)
Confirmed by yumdrea [7/4/2014 3:52:14 PM]
25x^2 - 4 = (5x + 2)(5x - 2)

98y^4 - 8y^2
= 2y^2(49y^2 - 4)
= 2y^2(7y + 2)(7y - 2)
