Simplifying Polynomial Expressions
This article will walk through the process of simplifying the polynomial expression (4x - x^3 + 3) - (2x^2 - 3x^3 + 1).
Understanding the Expression
The expression involves two sets of parentheses containing polynomial terms. The "-" sign between the parentheses indicates that we need to subtract the second set of terms from the first.
Simplifying the Expression
-
Distribute the negative sign:
- The negative sign in front of the second set of parentheses means we multiply each term inside the parentheses by -1.
(4x - x^3 + 3) - (2x^2 - 3x^3 + 1) = 4x - x^3 + 3 - 2x^2 + 3x^3 - 1
-
Combine like terms:
- Identify terms with the same variable and exponent and combine their coefficients.
4x - x^3 + 3 - 2x^2 + 3x^3 - 1 = (3x^3 - x^3) - 2x^2 + 4x (3 - 1)
-
Simplify further:
2x^3 - 2x^2 + 4x + 2
Final Result
The simplified form of the expression (4x - x^3 + 3) - (2x^2 - 3x^3 + 1) is 2x^3 - 2x^2 + 4x + 2.
