This week we started polynomials. The first time you look at polynomials you will probably have a heart attack. But they’re not as hard as you think. In this post I will teach you what a polynomial is and some vocabulary as well as how to do a question.
Type– Types of polynomials
Monomial- Consisting of one term.
Binomial- An algebraic expression of the sum or the difference of two terms.
Trinomial- An algebraic expression of the sum or the difference of three terms.
Polynomial- More than three parts/terms in the question.
Degree– The highest exponent
Coefficient-The number in front of a variable.
Constant- In Algebra, a constant is a number on its own.
Ex. 3 – 2x + 7y + 4y – 2x + 8z – 9
Step one: highlight or underline like terms to start grouping.
*like terms are numbers with the same ending.
3 – 2x + 7y + 4y – 2x + 8z – 9
Step two: Rearrange the numbers starting with the letter that comes first in the alphabet then go towards z. Do the constants last. Also go from greatest to least to stay organized.
– 2x – 2x + 7y + 4y + 8z + 3 – 9
Step three: Combine like terms.
– 4x + 11y + 8z – 6
Type: This equation is a polynomial because it has more than three terms.
Coefficients: -4, 11, 8 *the coefficients poses the sign before it. (+/-)
Degree: If they don’t have an exponent the degree will be one. The only one without the exponent as 1 will be the constant. The constant will have an exponent of 0.
