A) –7xy5 + 5x2y4 – 5x3y3 + 8x4y2 + 8x6
B) 5xy5 + 8x4y2 + x2y4 – 5x3y3 + 8x6
C) 8x6 + 5xy5 + 8x4y2 + x2y4 – 5x3y3
D) 8x6 + 8x4y2 – 5x3y3 + x2y4 – 7xy5

Respuesta :

–5x3y3 + 8x4y2 – xy5 – 2x2y4 + 8x6 + 3x2y4 – 6xy5 
Answer choice:
D) 8x6 + 8x4y2 – 5x3y3 + x2y4 – 7xy5

Answer:

Option D is correct that is [tex]8x^6+8x^4y^2-5x^3y^3+x^2y^4-7xy^5[/tex]

Step-by-step explanation:

we have to combine  the like terms

Like terms means the terms with same degree so,

for [tex]-5x^3y^3[/tex] has no like term since, x and y are of degree 3.

[tex]8x^4y^2[/tex] we have no like term again since there is no other x of degree 4

[tex]-xy^5[/tex] we have a like term [tex]-6xy^5[/tex]

[tex]-2x^2y^4[/tex] we have a like term [tex]3x^2y^4[/tex]

[tex]8x^6[/tex]we have no like term since, there is no other x of degree 6

Now, combining the like terms we will get

[tex]-5x^3y^3+8x^4y^2-xy^5-6xy^5-2x^2y^4+3x^2y^4+8x^6[/tex]

After simplification we will get

[tex]-5x^3y^3+8x^4y^2-xy^5-6xy^5-2x^2y^4+3x^2y^4+8x^6[/tex]

Rearranging the terms we will get

[tex]8x^6+8x^4y^2-5x^3y^3+x^2y^4-7xy^5[/tex]
