How to find the LC and degree of a polynomial by writing in standard form

The video tutorial explains the concept of standard form in polynomials, focusing on the arrangement of terms by power. It introduces the idea of like terms, which have the same base and power, and demonstrates how to combine them by adding their coefficients. The tutorial also covers the importance of maintaining the same exponent when adding like terms. Finally, it discusses the polynomial form, highlighting the degree and leading coefficient of a polynomial.

Why is it important for terms to have the same base and power to be combined?

What is the leading coefficient of the polynomial 5X^3 + 2X^2 + X?
