Simplifying the Expression: (4x^3 + 3x^4) - (x^4 - 5x^3)
This article will guide you through simplifying the expression (4x^3 + 3x^4) - (x^4 - 5x^3).
Step 1: Distribute the Negative Sign
The first step is to distribute the negative sign in front of the second set of parentheses. This means multiplying each term inside the parentheses by -1:
(4x^3 + 3x^4) + (-1)(x^4 - 5x^3)
This becomes:
(4x^3 + 3x^4) - x^4 + 5x^3
Step 2: Combine Like Terms
Now we can combine the terms with the same variable and exponent. Let's start with the x^4 terms:
(3x^4 - x^4) + (4x^3 + 5x^3)
Next, combine the x^3 terms:
2x^4 + (4x^3 + 5x^3)
Finally, combine the remaining terms:
2x^4 + 9x^3
Final Answer
Therefore, the simplified form of the expression (4x^3 + 3x^4) - (x^4 - 5x^3) is 2x^4 + 9x^3.
