Finding the Sum of Polynomials: (3x^2+4x-1)+(-2x^2-3x+2)
This problem involves adding two polynomials. Let's break it down step-by-step:
Understanding Polynomials
A polynomial is an expression consisting of variables and coefficients, combined using addition, subtraction, and multiplication, but never division by a variable.
Key terms:
- Variable: A symbol representing an unknown quantity (e.g., 'x').
- Coefficient: A number multiplying a variable (e.g., '3' in 3x^2).
- Term: A single variable, coefficient, or their product (e.g., '4x').
Adding Polynomials
To add polynomials, we combine like terms. Like terms have the same variable raised to the same power.
Steps:
-
Identify like terms:
- 3x^2 and -2x^2 are like terms
- 4x and -3x are like terms
- -1 and 2 are like terms
-
Combine like terms by adding their coefficients:
- (3x^2 - 2x^2) + (4x - 3x) + (-1 + 2)
-
Simplify the expression:
- x^2 + x + 1
Solution
Therefore, the sum of (3x^2 + 4x - 1) and (-2x^2 - 3x + 2) is x^2 + x + 1.
