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.
