I believe this is all right!

The given expressions can be simplified as (by grouping similar terms)

[tex] −12x^4 + 7x^3 + 6x^4 − 2x^3 =(−12x^4+ 6x^4) + (7x^3 − 2x^3)= 5x^3-6x^4 [/tex]

[tex] −5x^3 + 7x^4 + 4x^4 − 8x^3=(−5x^3 − 8x^3)+ (7x^4 + 4x^4 )=11x^4-13x^3 [/tex]

[tex] −2x^4 − 10x^3 + 4x^4 − 2x^3=(−2x^4 + 4x^4 )−( 10x^3 + 2x^3)=2x^4-12x^3 [/tex]

[tex] 15x^3 − 15x^4 + 13x^4 - x^3=(15x^3- x^3)+ (13x^4 − 15x^4 )=14x^3-2x^4 [/tex]

[tex] 7x^4 − 15x^3 + 12x^3 -2x^4=(7x^4 -2x^4) +( 12x^3- 15x^3)=5x^4-3x^3 [/tex]
