A polynomial is a monomial or a sum or difference of two or more monomials.
Polynomial function: A polynomial function is a function whose terms each contain a constant multiplied by a power of a variable.
P(x) = a0xn + a1xn-1 + .................+ an-2x2 + an-1x + an is a polynomial function
where a0, a1, a2,..., an are all real numbers and n is a non-negative integer.
Polynomial in one variable: a0xn + a1xn-1 + .................+ an-2x2 + an-1x + an is a polynomial in one variable.
A. 7x3 + 18x + 25
B. 7x3 + 6x + 5
C. 7x6 + 18x2 + 25
D. 7x6 + 6x2 + 5
Correct Answer: B
Step 1: The given polynomial expression (10x3 + 12x + 15) - (3x3 + 6x + 10) can be simplified as 7x3 + 6x + 5. [Combine like terms.]
