In summary, a polynomial is a mathematical expression containing variables and constants combined using addition, subtraction, and multiplication. To solve a polynomial equation, the expression must be simplified and set equal to zero before using algebraic techniques. The degree of a polynomial is the highest exponent of the variable, with negative exponents not allowed. A monomial is a polynomial with one term, while a polynomial can have multiple terms.

I can't seem to figure this out.

When a polynomial P(x) is divided by (2x+1) the quotient is x^2-x+2 and the remainder is 5. What is P(x)?

A hint: When 7 is divided by 3 the quotient is 2 and the remainder is 1.

If P divided by A has quotient Q with remainder R, P/A= Q+ R/A, then P= AQ+ R. You are told what A, Q, and R are. Just do the algebra to find P.

1. What is a polynomial?

A polynomial is a mathematical expression consisting of variables (such as x and y) and constants (such as numbers) combined using addition, subtraction, and multiplication, but not division. It can have multiple terms, with each term containing a variable raised to a non-negative integer power.

2. How do you solve a polynomial equation?

To solve a polynomial equation, you need to first simplify the expression by combining like terms and using the distributive property. Then, set the expression equal to zero and use algebraic techniques such as factoring, the quadratic formula, or synthetic division to find the values of the variable that make the equation true.

3. What is the degree of a polynomial?

The degree of a polynomial is the highest exponent of the variable in the expression. For example, if the expression is 2x^3 + 5x^2 + 3x + 1, the degree is 3 because x is raised to the power of 3 in the first term.

4. Can a polynomial have negative exponents?

No, a polynomial cannot have negative exponents. In a polynomial, the exponents must be non-negative integers, meaning they can only be 0, 1, 2, 3, and so on. If a polynomial has a term with a negative exponent, it is not considered a polynomial.

5. What is the difference between a monomial and a polynomial?

A monomial is a polynomial with only one term, while a polynomial can have multiple terms. For example, 3x^2 is a monomial, while 3x^2 + 5x + 2 is a polynomial with three terms.
