Answer:

[tex]-3x^4+3x^3+8x^2-2x-5[/tex]

Step-by-step explanation:

We have the expression [tex](-2x^4-2x^3+8x^2+2)-(x^4-5x^3+2x+7)[/tex] we can rewrite it as:

[tex]-2x^4-2x^3+8x^2+2-x^4+5x^3-2x-7[/tex]

We have to reorder and group similar terms:

[tex]-2x^4-2x^3+8x^2+2-x^4+5x^3-2x-7=\\=(-2x^4-x^4)+(-2x^3+5x^3)+(8x^2)+(-2x)+(2-7)[/tex]

[tex]=(-3x^4)+(3x^3)+(8x^2)+(-2x)+(-5)\\=-3x^4+3x^3+8x^2-2x-5[/tex]

Then the answer in standard form is:

[tex]-3x^4+3x^3+8x^2-2x-5[/tex]
