Hello,

You cannot. Expressions like these are best handled by hand.

Hope it helps.

Hi,

a 6ya expert can help you resolve that issue over the phone in a minute or two.

best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).

click here to download the app (for users in the US for now) and get all the help you need.

goodluck!

If a is the name of a PIC, GDB, MAC, FIG, etc., a+1 is invalid. Use a different variable name in the expression or delete the variable.

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.

I am afraid you cannot do that with the TI83/84 Plus SE. The newer OS
allows you to get results expressed as fractions, but not radicals.
Sorry.

Your question seems to imply that you can do algebra with this calculator but that is impossible, unless you stored numerical values in variables a and b.**In that case that is not doing algebra.**

The Calculator does not have a Computer Algebra System (CAS), and cannot perform algebraic operations with variables. However if you enter some expression with variables, it can solve for one unknown after it prompts you for the values of the others

This calculator cannot manipulate algebraic expressions. You can enter an expression and generate a table of values. You can enter an equation in one unknown and solve it. But you cannot do algebra.

You would need a calculator that has a Computer Algebra System (Algebra FX 2.0, or ClassPad 300/330). Sorry.

This calculator cannot do algebra ( manipulating expressions with letter symbols) . It does not have a CAS (computer Algebra System). All it can do is evaluate (find the numerical value of) expressions typed in. If it has the appropriate keys to enter variables such as A,B,C, or X and Y., and you entered an expression with variables it will use the numerical values stored in the variables. If you have not stored anything in a variable, it is given the value 0 by default.

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)

(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)

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

This is very basic scientific calculator and you cannot use it with variables.

As to your equation (if you want to solve it) it is much simpler to do so with pen and paper.

Write it as

3y-6=-7y +4

Take the 6 from the left to the right where it becomes +6, Thus

3y=-7y+4+6

3y=-7y+10

Take the -7y term from the right to the left side, where it becomes +7y

3y+7y=10 or 10y=10.

The solution is clearly y=1.

Hello,

This calculator cannot handle symbolic algebra.

Use the rules to simplify the expressions: Get rid of the parentheses using distributivity od multiplication with respect to addition; group similar terms (terms with x, terms without x).

Hope it helps.
