Question about Casio FX-115ES Scientific Calculator

How do I factor using the fx-115 ES calculator? would a problem like 9x^2+24x+16-Z^2 be solvable on this calculator? If not, does Casio sell any calculators that would help me factor this equation?

No, your calculator cannot factor polynomials. You need a calculator that has a CAS (computer Algebra System)
Yes Casio sells calculators with CAS: The FX-Algebra 2.0 and 1.0, the FX-9860GPLUS/GII SD, the GRAPH85 or 80 and the Graph 100+. You also have the CLASSPAD Series 300PLUS and 330.
TI and HP also have CAS calculators.

Texas Instruments
TI 89 /Titanium, Voyage 200PLT, TI92PLUS (discontinued), TI Inspire CAS.

HP 48G/G+/GX, HP40G, HP49G/G+ and the top of the line HP50G

How can i write this in my calculator example. 2x=10 the answer is x=5 but how can i put x in the calculator

What you want to do is solve the linear equation 2x=10 to find the value of the unknown x that makes the equality true. Solving an equation usually involves rearranging therms, factors and so on. However your calculator was not designed to handle the solution of equations, no matter how simple they are.
Some Casio scientific calculators can solve some types of equations (polynomials of degree 2 or 3, simultaneous linear equations in up to 3 unknowns). These are the FX-115 ES (Plus) and FX-991 ES (Plus C). Other equivalent models are sold in the world under different names.

Can i plot graphs using fx 115 es?

The fx-115ES is not a graphics calculator so it will not display graphs on its screen. You can use it to make graphs by calculating the points and plotting them on graph paper.

How do i get my casio fx-115 ES to let me use sec csc cot

The calculator doesn't have those functions built-in. Use the relationships sec(x) = 1/cos(x), csc(x) = 1/sin(x), and cot(x) = 1/tan(x).

Casio FX-115 ES: SIN,COS,TAN (answer isnt correct)

It may be due to the angle unit used. You can have angles in degrees, in radians, and in grads. You should set the default angle unit to waht you problem calls for.
To set degree as default SHIFT MODE 3
To set radians as default SHIFT MODE 4
To set grads as default SHIFT MODE 5

The values of angles calculated by the inverse trigonometric functions are in the default unit that is set . This may be the source of the wrong answers that you get.

Hope it helps.

Inputing factors on a casio fx-115es calculator

Unless I am failing to understand your problem, just combine like terms to get:
9x^2+2x+4 and then enter those coefficients into the quadratic solver.
That will get you the two answers -- both of them will be complex.
If you wanted to turn those two answers into factors (complex) of the original equation simply
change the signs on each and put an x in front.
Of course, the quadratic formula would also work.
