Final Answer
The given expressions can be simplified as follows:
1. 2x³ - 7x³ = -5x³
2. 4 + 7x
3. 11x³ - 4x
Explanation
The expressions provided are:
1. 2x³ - 7x³
2. 4 + 7x
3. 11x³ - 4x
1. The first expression, 2x³ - 7x³, can be simplified by combining the like terms. Since both terms have the same variable raised to the power of 3, we can subtract the coefficients: 2x³ - 7x³ = -5x³.
2. The second expression, 4 + 7x, is already in its simplest form and cannot be further simplified. It is an algebraic expression consisting of a constant term (4) and a linear term (7x).
3. The third expression, 11x³ - 4x, is also in its simplest form. It contains two terms: 11x³, which is a cubic term, and -4x, which is a linear term.
In summary, the given expressions are simplified as follows:
1. 2x³ - 7x³ = -5x³
2. 4 + 7x
3. 11x³ - 4x
These expressions have been simplified according to the algebraic rules of combining like terms, and the resulting forms represent their simplest forms.
