(2x^2 + 3x + 7)^3
= (2x^2 + 3x + 7)(2x^2 + 3x + 7)(2x^2 + 3x + 7)
= (2x^2 + 3x + 7)(4x^4 + 6x^3 + 14x^2 + 6x^3 + 9x^2 + 21x + 14x^2 + 21x + 49)
= (2x^2 + 3x + 7)(4x^4 + 12x^3 + 37x^2 + 42x + 49)
= 8x^6 + 24x^5 + 74x^4 + 84x^3 + 98x^2 + 12x^5 + 36x^4 + 111x^3 + 126x^2 + 147x + 28x^4 + 84x^3 + 259x^2 + 294x + 343
= 8x^6 + 36x^5 + 138x^4 + 279x^3 + 483x^2 + 441x + 343
