Question

Add the Polynomials and simplify:
(-7x³ +8x² +x+ 3) + (x¹ - 2x³ - 7x² + 3)

Answer 1

To add and simplify the polynomials (-7x³ + 8x² + x + 3) + (x¹ - 2x³ - 7x² + 3), we need to combine like terms.

First, let's rearrange the terms in descending order of exponents:

-7x³ + 8x² + x + 3 + x¹ - 2x³ - 7x² + 3

Now, let's combine like terms:

(-7x³ - 2x³) + (8x² - 7x²) + (x¹ + x) + (3 + 3)

Simplifying each group of like terms:

-9x³ + x² + 2x + 6

So, the sum of the polynomials (-7x³ + 8x² + x + 3) + (x¹ - 2x³ - 7x² + 3) is -9x³ + x² + 2x + 6.
