How do you Simplify Expressions
How do you Simplify Expressions
The equations section of QuickMath al ows you to solve and plot virtually any equation or
system of equations. In most cases, you can find exact solutions to your equations. Even
when this is not possible, QuickMath may be able to give you approximate solutions to almost
any level of accuracy you require. It also contains a number of special commands for dealing
with quadratic equations.
Solve
The Solve command can be uses to solve either a single equation for a single unknown from
the basic solve page or to simultaneously solve a system of many equations in many
unknowns from the advanced solve page. The advanced command al ows you to specify
whether you want approximate numerical answers as wel as exact ones, and how many digits
of accuracy (up to 16) you require. It also al ows you to eliminate certain variables from the
equations.
Plot
The Plot command, from the Graphs section, wil plot any function of two variables. In order to
plot a single function of x, go to the basic equation plotting page,

where you can enter the equation and specify the upper and lower limits on x that you want
the graph to be plotted for. The advanced plotting page allows you to plot up to 6 equations on
the one graph, each with their own color. It also gives you control over such things as whether
or not to show the axes, where the axes should be located, what the aspect ratio of the plot
should be and what the range of the dependent variable should be. Al equations can be given
in the explicit y = f(x) form or the implicit g(x,y) = c form.
Quadratics
The Quadratics page contains 13 separate commands for dealing with the most common
questions concerning quadratics. It al ows you to : factor a quadratic function (by two different
methods); solve a quadratic equation by factoring the quadratic, using the quadratic formula or
by completing the square; rewrite a quadratic function in a different form by completing the
square; calculate the concavity, x-intercepts, y-intercept, axis of symmetry and vertex of a
parabola; plot a parabola; calculate the discriminant of a quadratic equation and use the
discriminant to find the number of roots of a quadratic equation. Each command generates a
complete and detailed custom-made explanation of all the steps needed to solve the problem.
Whenever a problem can be simplified, you should simplify it before substituting numbers for
the letters. This wil make your job a lot easier! To simplify an algebraic expression:
2(3+x)+x()1-4x)+5
1. Clear the parentheses.
2. Combine like terms by adding coefficients.
3. Combine the constants.
You need the TI-Nspire CX CAS. CAS stands for Computer Algebra System. With the
CAS, the calculator can preform symbolic algebra which means in can simplify
expressions, simplify radicals, return answers in terms of pi and e, and also preform
numerous calculus functions such as derivatives and indefinite integrals. For me, the
Nspire without the CAS is a huge waste of money.

What you have without the CAS is essentially an expensive TI-84 with a color screen,
file management system, and a much improved TI-Basic programming language.
In layman's terms, unless you have miss-typed the full title of you calculator, you
cannot simplify expressions with your calculator.
If you do have a the CAS version, it wouldn't be giving you an error. Also when you're
in the calculator app, press Menu, then 3:Algebra, and you'll see all the functions for
simple algebraic expressions and equations.
