*Hello! Grade 10 Pre-Cal*

*Today in class we started with polynomials which is our first Unit of the course.*

*Mr. Kurapatwa thought as a little bit of Definition of Polynomials.*

*As we know that our first unit is polynomial, So we have to know the definition of polynomial!*

*1. Polynomials: is an algebraic expression of one or more terms*

*e.g. 2x+3y or x^2 - 5x+4*

*2. Monomial: is an algebraic expression of one term*

*e.g. 6x or 5ab or y*

*3. Binomial: is an algebraic expression of two terms*

**We have to remember that any expression with two terms is a Binomial*

*e.g. x-y or x + 4*

*4. Trinomial: is an algebraic expression of three terms*

*e.g. 2x + 5y -4*

**We also learn 5 other Definition**

1) Terms: is a symbol or group of symbols separated from other symbols bya plus or minus sign.

e.g. 3x - 5y + 7xyz in this expression we know that there are three terms, note that terms may contain several numbers and letters.

2) Coefficient: The numeric factor of a term (a number with a variable)

* for example 3x + 5y -4* the coefficient in this expression are 5 & 4

3) Sum: The result of Adding two or more number

e.g. The sum of 2 and 3 is? so we know that if we add 2 and 3 we get 5

4) Product: The result of Multiplying two or more numbers

e.g. the product of 7 and 3 is? so what we will do is to multiply 7 and 3, which will give us 49.** **

**Time to Practice!!**

*Adding and Subtracting Polynomials*a. 7x-y-2x+3y? (when we are adding or subtracting polynomials we combine the like terms which looks the same.)

**5x+2y**

*2. (4x-2y-4)-(-3x-2y+5) *i think this is little bit trickier**

**7x-9**ans

*Multiplying and Dividing of Polynomials.*

**1. 2(x+y)****2.**

the coefficient and cancel the like terms

variable.

**Which Will give as 8x**
