A monomial is an algebraic expression that consists of only one term,
3a, 4f, 5x.....
A polynomial consists of two or more terms:
4x + 7y
Adding and Subtracting Polynomials:
When adding/subtracting polynomials, you need to group similar terms.
3a³-6a²+ 5a³+12a²= 8a³+6a²
12X² + X² = 13X²
4Y - 5Y= -1Y
17X² + 2X + 8X²+ 5X = 25X²+ 7X
When multiplying or dividing polynomials, you need to use the rules of exponents.
3X(X³+ 4X²) = 3X⁴+ 12X³
4Y⁴(Y²+ 6Y)= 4Y⁶+ 24Y⁵
