x^2 + 3x - 28 = 0;
(x + 7)(x - 4) = 0;
x + 7 = 0; x = -7;
x - 4 = 0; x = 4
x = {-7, 4}

(6x^2 – 25x – 10) ÷ (3x + 2)
= (6x^2/3x + 2) + (-25x/3x + 2) + (-10/3x + 2)
= 2x - 29/3 R. 28/3

(-3x^2 + 9x^4 - 8 - 5x^3) - (-4 - 3x^3 + 4x^4 + 8x^2)
= -3x^2 + 9x^4 - 8 - 5x^3 + 4 + 3x^3 - 4x^4 - 8x^2
= 5x^4 - 2x^3 - 11x^2 - 4

To simplify the given polynomial, combine like terms:
cd^2 + 6a^2c^2 - 8cd^2 + a^2c^2
Combine the terms with the same variables:
(cd^2 - 8cd^2) + (6a^2c^2 + a^2c^2)
Combine the coefficients:
-7cd^2 + 7a^2c^2
So, the simplified polynomial is -7cd^2 + 7a^2c^2.
