A REQUIREMENT FOR MATHEMATICS 10 1ST QUARTER

* A Mathematical expression that contains one or more terms. It is in the form of ax^n where a is a real number and n is a positive integer.

* an expression of more than two algebraic terms, especially the sum of several terms that contain different powers of the same variable(s).

* a mathematical expression involving a sum of powers in one or more variables multiplied by coefficients.

axn + bxn-1 + . . . + rx + s = 0, where a, b, . . . , r and s are constants.

Solve the equation. x4-20x2+64=0Solution:

x4-20x2+64=0

(x2)2 – 20 (x2) +64=0

(x2-16)(x2-4)=0

x2- 16=0 x2- 4=0

x2= 16 x2=4

x= ±4 x= ± 2

Solve the equation. x5+10x3+9x=0Solution:

x5+10x3+9x=0x(x4-10x2+9)=0

x((x2)2-10(x2)+9)=0

x((x2-9)(x2-1))=0

x=0; x2-9=0; x2-1=0x=0; x2=9; x2=1x=0; x= ±3 x= ±1

* Graphing the polynomials only need the information of completing the list of all zeroes (including multiplicity) for the polynomial

* an expression of more than two algebraic terms, especially the sum of several terms that contain different powers of the same variable(s).

FIRST PROPERTY SECOND PROPERTY* There are no holes or breaks in the graph

and there are no sharp corners in the graph

* The graphs of polynomials will always be nice smooth curves.

* The “humps” where the graph changes direction from increasing to decreasing or decreasing to increasing are often called turning points

IF X=R IS A ZERO OF THE POLYNOMIAL P(X) WITH THE MULTIPLICITY K,

* If k is odd then the x-intercept corresponding to x=r will cross the x-axis

* If k is even then the x-intercept corresponding to x=r will only touch the x-axis and not actually cross it.

* Furthermore, if k>1 then the graph will flatten out at x=r

IF X=R IS A ZERO OF THE POLYNOMIAL P(X) WITH THE MULTIPLICITY K,

* If k is odd then the x-intercept corresponding to x=r will cross the x-axis

* If k is even then the x-intercept corresponding to x=r will only touch the x-axis and not actually cross it.

* Furthermore, if k>1 then the graph will flatten out at x=r

* The degree of the polynomial is 3 and there would be 3 zeros for the functions.

* Make a table of values to find several points.

* Plot the points and draw a smooth continuous curve to connect the points
