What is Polynomial Addition?
Polynomial addition is a mathematical operation that involves combining two or more polynomials by adding their corresponding terms. In this article, we will focus on adding two polynomials: 5x³+2x²y-10x+16 and x³-4x²y+9-17.
Step 1: Write the Polynomials
The first polynomial is 5x³+2x²y-10x+16, and the second polynomial is x³-4x²y+9-17. To add these polynomials, we need to write them in a vertical format, with the terms of each polynomial lined up.
5x³ + 2x²y - 10x + 16
+ x³ - 4x²y + 9 - 17
Step 2: Add the Like Terms
Like terms are terms that have the same variable and exponent. In this case, we have two like terms: 5x³ and x³, and two like terms: 2x²y and -4x²y.
5x³ + 2x²y - 10x + 16
+ x³ - 4x²y + 9 - 17
-------------------------
(5x³ + x³) + (2x²y - 4x²y) + (-10x) + (16 + 9 - 17)
Step 3: Simplify the Expression
Now, we can simplify the expression by combining the like terms.
(5x³ + x³) + (2x²y - 4x²y) + (-10x) + (16 + 9 - 17)
= 6x³ - 2x²y - 10x + 8
Q&A
Q: What is the final answer to the polynomial addition problem?
A: The final answer is 6x³ - 2x²y - 10x + 8.
Q: How do I add polynomials with different variables?
A: To add polynomials with different variables, you need to combine the like terms. If the variables are different, you cannot combine the terms.
Q: Can I add polynomials with negative coefficients?
A: Yes, you can add polynomials with negative coefficients. When adding polynomials with negative coefficients, you need to change the sign of the coefficient when combining like terms.
Q: How do I simplify a polynomial expression?
A: To simplify a polynomial expression, you need to combine the like terms. This involves adding or subtracting the coefficients of the like terms.
Q: What is the difference between adding and subtracting polynomials?
A: The difference between adding and subtracting polynomials is that when subtracting polynomials, you need to change the sign of the terms in the second polynomial.
