Is 2 a polynomial?
Yes, f(x) = 2 is a polynomial of degree 0 (because there are no x terms).
How do you classify polynomials based on degree?
Oh, dude, it's like super simple. So, basically, you classify polynomials based on their degree, which is the highest power of the variable in the polynomial. If the highest power is 1, it's a linear polynomial; if it's 2, it's quadratic; and if it's 3, it's cubic. Anything beyond that, like a fourth-degree polynomial or higher, we just call them "higher-degree polynomials." Easy peasy, lemon squeezy!
Can two third-degree polynomials be added to produce a second-degree polynomial?
Yes. If the coefficient of the third degree terms in one polynomial are the additive inverses (minus numbers) of the coefficient of the corresponding terms in the second polynomial. Eg: 3x3 + 2x2 + 5 and -3x3 + x - 7 add to give 2x2 + x - 2
Why it is not possible to add two polynomials of degree 3 and get a polynomial of 4?
When you add polynomials, you simply add the coefficients of the variable taken to the same degree. For example (x3 + 2x2 + 3x + 4) added to (2x3 - 4x2 + x -2) would give you [(1+2)x3 + (2-4)x2 + (3+1)x + (4-2)] or 3x3 - 2x2 + 4x + 2 You would get a fourth degree polynomial by multiplying this one by x. Another way to think of it: If you add 1 apple and 3 apples (like one times x2 and 3 times x2) you still get apples, not watermelons.
Describe a polynomial in one variable?
A polynomial has 2 or more variables. It can also have a negative exponent and a fractional exponent. It's different from a monomial.****BrandonW****
