Answer 1

Answer:

5x^7 + 4x^6 + 1

Step-by-step explanation:

To solve, all you need to do is collect and combine like-terms (terms with the same variables and powers):

The equation is:

• (3x^7 - 4x^6 + 3) + (2x^7 + 8x^6 -2)

Collect like-terms:

• 3x^7 and 2x^7
• -4x^6 and 8x^6
• 3 and -2

You can rewrite the equation as:

• (3x^7 + 2x^7) + (-4x^6 + 8x^6) + (3 - 2)

Now combine the like-terms:

• 3x^7 + 2x^7 = 5x^7
• -4x^6 + 8x^6 = 4x^6
• 3 - 2 = 1

Substitute the found sums and differences into the equation:

• (3x^7 + 2x^7) + (-4x^6 + 8x^6) + (3 - 2) = 5x^7 + 4x^6 + 1
