5x^4+3x^2-2x
-5x^4-3x^2+9x
_______________
0x^4+x^2+7x
is this right?
Are you adding these two equations?
If so,
5x^4 + 3x^2 - 2x
-5x^4 - 3x^2 + 9x
-------------------
0 + 0 + 7x
The answer is 7x
no im subtracting
To determine whether the expression is simplified correctly, we need to simplify each term and combine like terms:
From the first expression: 5x^4 + 3x^2 - 2x
From the second expression: -5x^4 - 3x^2 + 9x
Now, let's add the two expressions together:
(5x^4 + 3x^2 - 2x) + (-5x^4 - 3x^2 + 9x)
When adding these expressions, we need to combine like terms. Like terms have the same variable raised to the same exponent.
For example:
- The terms 5x^4 and -5x^4 have the same variable (x) raised to the same exponent (4).
- The terms 3x^2 and -3x^2 also have the same variable (x) raised to the same exponent (2).
Adding these like terms, we get:
(5x^4 + (-5x^4)) + (3x^2 + (-3x^2)) + (-2x + 9x)
Simplifying further, we have:
0x^4 + 0x^2 + 7x
Therefore, the simplified expression is 0x^4 + x^2 + 7x.
Yes, your simplified expression is correct.
