### 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

### Need to know how to add. Simplify, if possible. x+1/x+x/x+1

Sorry, this calculator can only manipulate numerical values, not algebraic symbols. It does not a have a CAS (Computer Algebra System).

### I want to know if you can factor trinomials on ti-84 plus silver edition

The calculator itself does not have a computer algebra system and therefore cannot handle algebraic expressions.

### What is algebra?

It's math...Why is this in the computer section? The only thing that I know of that Algebra has to do with computers is with programming. You need to know it for variables and such...programming is very mathematical. But that's the only reason I can think of algebra with computers. Unless your speaking of some program.

### (squareroot 5 + squareroot 2) (squareroot 5 - squareroot 2) how do you do this? I dont know how to work this out sorry seems dumb.

let square root 5 = X and square root 2 = Y

then the equation will be (X+Y) (X - Y)

which is = to X^2 - Y^2

= 5 - 2 = 3 is the answer.

pls ask any doubts if u have any.dont forget to rate this solution

### How to do matrix with variables?

Hi,
If I understand correctly you want to perform matrix calculations on matrices the coefficients of which may be numbers and/or letters (variables, parameters). While you can calculate on numerical matrices, you cannot do so with matrices with non numerical coefficients. this calculator does not know symbolic algebra.

For symbolic algebra and calculus you would need a calculator with a CAS, Computer Algebra System. Exemples of those are the TI89, Ti92, Ti Voyage 200 PLT, The Casio FX-Algebra, the Casio ClassPad, HP48S/X/G/GX/G+, HP49G/49G+, HP50G, HP48GII etc.

Hope it Helps.
Thanks for using FixYa and for rating this solution.

### Calculator help for algebra 1

cryshug24 the mode(s) you want to use is mth IO and line IO for algebra. push the shift mode then #1. to write out a long equation push shift mode #2. you have to keep playing between the two modes to get the correct answer.
