Simplifying Polynomial Expressions
This article will guide you through the process of simplifying the polynomial expression (6b^3+6-b^4)-(8b^3-6b^4+2).
Understanding the Steps
-
Distribute the negative sign: The minus sign in front of the parentheses means we multiply each term inside the second set of parentheses by -1.
-
Combine like terms: After distributing the negative sign, we can combine terms with the same variable and exponent.
Simplifying the Expression
Let's break down the simplification process step-by-step:
-
Distribute the negative sign:
(6b^3 + 6 - b^4) - (8b^3 - 6b^4 + 2) = 6b^3 + 6 - b^4 - 8b^3 + 6b^4 - 2
-
Combine like terms:
(6b^3 - 8b^3) + (-b^4 + 6b^4) + (6 - 2) = -2b^3 + 5b^4 + 4
Final Simplified Expression
Therefore, the simplified form of the polynomial expression (6b^3+6-b^4)-(8b^3-6b^4+2) is 5b^4 - 2b^3 + 4.
