The simplified expression for 2x^2 - 7x + 4 + 3x^2 + 5x - 7 is 5x^2 - 2x - 3. Combining like terms by grouping and summing coefficients, the final result is a quadratic polynomial in descending order of degree.
To simplify the expression 2x^2 - 7x + 4 + 3x^2 + 5x - 7, we combine like terms by grouping and then summing coefficients of similar powers of x.
Grouping the terms: (2x^2 + 3x^2) + (-7x + 5x) + (4 - 7)
Combine like terms within each group: 5x^2 - 2x - 3
The final simplified expression is 5x^2 - 2x - 3, where the terms are organized in descending order of degree.
This result is obtained by adding the coefficients of like terms, resulting in a simplified quadratic expression. The polynomial 5x^2 - 2x - 3 represents the simplified form of the original expression.
