Your scientific calculator is unable to solve complex equation with complex coefficients. You should try to solve by hand directly using the quadratic formula or by factoring the polynomial in z failing that, another way would be to set z=x+iy, substitute this for z, carry out the algebra and try to separate real and imaginary parts. But your two equations will constitute a system of two quadratic equations. I am not aware of any general method to solve coupled nonlinear equations. Good luck.
Factoring is one of the hardest problems of elementary algebra. Not all calculators are designed to handle it. To be able to factor on a calculator, the calculator must have a COMPUTER ALGEBRA SYSTEM. Some expensive calculators have that feature. Most calculators (scientific ones) do not have a CAS. Consult an elementary (beginning) algebra texbook to read on and understand factoring. For homework it is more efficient to use standard techniques or a combination of techniques to factor polynomials.
Sorry, but no! it is not capable of factoring anything. It can however solve for the roots of a polynomial equation.Write your polynomial as P(X)= a(X² +(b/a)X+c/a) =0. Use the calculator to solve the polynomial equation X² +(b/a)X+c/a =0 and find the roots X1, and X2. You will then be able to write the original polynomial as P(X)=a(X-X1)(X-X2). Beware that by using the calculator, the values of the roots are approximate.
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 InspireCAS.
Hewlet-Packard HP 48G/G+/GX, HP40G, HP49G/G+ and the top of the line HP50G
The Casio FX-115ES does not have a Computer Algebra System (or CAS), so it is incapable of factoring polynomials. As to simplifications, the only ones that you can get with the FX-115ES are the display of fractions in their irreducible forms.
Hello, The Casio FX-300ES does not handle symbolic algebra. So it cannot factor a general polynomial expression. The methods can be found in any book on Algebra. However if you are interested in approximate factorization of quadratic and cubic polynomials, you can use the calculator to do that. It can solve aX^3 +bX^2+cX+d =0 and the quadratic equations.
If you want to factor a cubic polynomial P3(X) = aX^3+bX^2+cX+d , you write the corresponding cubic equation as aX^3+bX^2+cX=d =0 , then you divide all terms of the equation by a to obtain
You use the calculator to solve (approximately) this equation. Suppose you find the 3 roots X1,X2,and X3. Then the polynomial X^3+(b/a)X^2+(c/a)X+(d/a) can be cast in the factored form (X-X1)(X-X2)(X-X3) and the original polynomial P3(X) can be written as
P3(X) = a*(X-X1)(X-X2)(X-X3)
You can handle the quadratic polynomial the same way.
P2(X) =a*(X-X1)(X-X2) where X1, X2 are the two real roots
