ur an idiot
To subtract polynomials, we need to combine like terms. In this case, we have:
(5x^4 + 3x^2 - 2x) - (-5x^4 - 3x^2 + 9x)
To simplify, we can distribute the negative sign in front of the second polynomial:
5x^4 + 3x^2 - 2x + 5x^4 + 3x^2 - 9x
Now, let's combine the like terms:
(5x^4 + 5x^4) + (3x^2 + 3x^2) + (-2x - 9x)
This simplifies to:
10x^4 + 6x^2 - 11x
So, no, the result is not 0x^4 + x^2 + 7x. It should be 10x^4 + 6x^2 - 11x.
