SOURCE: how to solve a quadratic formula using a casio

Hello,

The calculator does not have a solve program, but you can still use it to solve the quadratic equation with a little effort. If you know the therory skip toward the end.

Let aX^2+bX+C=0

1. First calculate the discriminant usually called Delta and given by

Delta =b^2 -4*a*c store the value in the variable D

If Delta is positive you have two roots X1 and X2 given by

X1=(-b+square root of Delta)/(2*a)

X2=(-b- square root of Delta)/(2*a)

If Delta is equal to 0, X1=X2=-b/(2*a)

If Delta i negative, no real solutions exist

You only solve if Delta is positive or equal to 0.

Putting in the values of a, b, and c

value of a (put you number) [SHIFT][STO] A

value of b (put your value) [SHIFT][STO] B

value of c (put you value) [SHIF][STO] C

[ALPHA] B [X^2] -4[x][ALPHA] A [x][ALPHA] C [=]

Value of delta is displayed. If it is positive, you store its square root in D

[Square root] [ANS] [SHIFT][STO] D ;

Calculate 1/(2*a) and store in variable F

1./(2[x] ALPHA A) [SHIFT][STO] F

To obtain X1

[ALPHA] F [x] ( (-) ALPHA B + ALPHA D ) [=]

To obtain X2

[ALPHA] F [x] ( (-) ALPHA B - ALPHA D ) [=]

Be careful: the (-) is the change sign not the regular minus sign.

Hope it helps.

For common logs (logs in base 10) use the 10^x function : Press [SHIFT] [Log] to access it.

For natural logs, use the exponential function. Press [SHIFT][ln] to access it.

Sorry, It is not possible to solve equations on the Casio FX-82 ms. Try the Casio FX-115 ES/ FX-115 ES Plus, FX-991ES/ FX-881 ES Plus C.

It can calculate numerical values of derivatives of functions and definite integrals but it does not solve differential equations.

The Casios FX-115 ES , FX-115 ES PLus, FX-991 ES, FX-991 ES Plus C can perfom numerical differentiation at a point, and numerical integration between two given limits.

Sorry, the Fx-115W is unable to solve equations of any type. In addition to that, the more sophisticated Casios such as the FX-991 ES solve linear equations of no more than 3 variables.

Sep 09, 2012 | Casio FX-115W Plus Calculator

The FX-901 calculator seems to be the equivalent of the FX 260 Solar sold in North America. It does fraction calculations, permutation, statistics but lack the Equation Solver.

You cannot use it to solve equations.

Casio Scientific calculators that can handle equation solving are the FX-115 and FX-991.

Simplify your first equation by dividing all its terms by 3, then use elimination to carry out the solution by hand.

I am not quite sure what you mean by ``solve f(x)=100x-64*x^2+48*x^3 for different value of x``. Do you want to find the roots of the cubic equation 0=100x-64*x^2+48*x^3 , or do you want to generate values of f(x) for different values of the variable x.

For the first case, use the SOLVE program,

for the second, use the TABLE computational mode: Press MODE and select TABLE, then enter the expression to the right of the equal sign. In TABLE, X is the default variable.
