What does polynomial function mean?


Let us backtrack so as to better jump.
An algebraic expression may contain one or several algebraic terms, separated by a plus sign or a or a minus and a sign.
Each algebraic term is the product of a constant coefficient and a power of some variable, or the powers of several variables.
Example of an algebraic term 3(x^2)(y^6)....
If the exponents of the various powers are positive integers, the term is called a monomial. In short no square roots, or fractionary powers of the variables appear in monomials. Thus 2/x, 3SQRT(x), or 1/x^5 are not monomials.
Finally, a polynomial is an algebraic expression made up of one or more monomials.
Example P(X)=(1/3)X^7-(SQRT(5)*X^4+ 16X-25 is a polynomial of degree 7 in the indeterminate/variable X
Q(X,Y)= 3(X^3)*Y^2 + 4X-5Y+10 is a polynomial of degree 5 in the variables X and Y.

(a + 2b)(a2 - 2ab - 4b2)


I believe that the algebraic expression should be written as:
(a + 2b)(a^2 - 2ab - 4b^2)

which can be rewritten as:
(a + 2b)^2 * (a - 2b)


The simplified form of this expression is:
(a^3 - 2a^2b - 4ab^2 + 2a^2b - 4ab^2 - 8b^3)

which can then be further simplified as:
(a^3 - 8b^3)

Wat is special product


Here, We deal with Some Special Products in Polynomials.

Certain products of Polynomials occur more often
in Algebra. They are to be considered specially.

These are to be remembered as Formulas in Algebra.

Remembering these formulas in Algebra is as important
as remembering multiplication tables in Arithmetic.

We give a list of these Formulas and Apply
them to solve a Number of problems.

We give Links to other Formulas in Algebra.

Here is the list of Formulas in
Polynomials which are very useful in Algebra.
Formulas in Polynomials :

Algebra Formula 1 in Polynomials:

Square of Sum of Two Terms:

(a + b)2 = a2 + 2ab + b2
Algebra Formula 2 in Polynomials:

Square of Difference of Two Terms:

(a - b)2 = a2 - 2ab + b2
Algebra Formula 3 in Polynomials:

Product of Sum and Difference of Two Terms:

(a + b)(a - b) = a2 - b2
Algebra Formula 4 in Polynomials:

Product giving Sum of Two Cubes:

(a + b)(a2 - ab + b2) = a3 + b3
Algebra Formula 5 in Polynomials:

Cube of Difference of Two Terms:

(a - b)3 = a3 - 3a2b + 3ab2 - b3 = a3 - 3ab(a - b) - b3
Algebra Formula 8 in Polynomials:


Each of the letters in fact represent a TERM.

e.g. The above Formula 1 can be stated as
(First term + Second term)2
= (First term)2 + 2(First term)(Second term) + (Second term)2

How i can find eigenvalue whit algebra calculator


In answering your other question I did make a mistake: I looked at the wrong version of the manual. The Algebra FX 2 Plus does solve for eigenvalues. Under the CAS. Here is a screen capture to help you.

I need assistance understanding this algebra equation and the steps to solve it. 7+(9-5x)=5(2-x)


this is a simple algebraic equation in which we have to calculate the value of 'x' using simple operations

7+(9-5x)=5(2-x)


step 1(pen the brackets) 7+9-5x=10-5x
step 2(add 7 and 9) 16-5x=10-5x

now as 5x gets cancelled both the sides of the equal sign therefore no solution of this algebraic equation exist.

Calculator is not expanding or factorising algebraic expressions as should. Gives answers in curly brackets which seem unrelated.


I am somewhat puzzled at your affirmation concerning factoring and expanding algebraic expressions. The TINspire does not do symbolic algebra, only the TI Nspire CAS does.
If you have the TINspire CAS, (version 2.x) you can
  1. press the HOME button, then select A:Calculate.
  2. In one of the pages, press MENU.
  3. Select [3:Algebra]
  4. Use Down Arrow or enter the number 2:Factor, or 3:expand
  5. In the command line, expand( , complete the command by entering the expression, close the right parenthesis and press [ENTER].
  6. The calculator should give you the expanded result.

2(x+1)=2


If this is an algebra type problem where you want a value for x then x=0.If you are asking if it is times or plus then it is times.
algebra: 2(0+1)=2;2(1)=2 The parentheses represents multiplication
plus or times;2x1=2
