Week 8 — Math 10

This week, we began to learn chapter5–Polynomial. I think there are lots of fun to solve the problems of polynomial.

I felt so confused about lots of new words. But now I got those words.

Variable: the letter in a polynomial.

Polynomial: (Note)The exponent of any variable must be a positive integer.

Degree: The degree of a polynomial is the degree of the term with highest degree.

The leading coefficient of a polynomial in a single variable is the coefficient of the term with highest power of the variable.

Zero pair: a pair of terms that combined simplify yo zero.

Distribute: Multiplying a sum or difference by a common number. Used to remove brackets from an expression.

In this week, I also learnt how to use Area Diagram, this really helpful when I am doing those questions.
