Without using legrange multipliers, determine the dimensions of a rectangular box,open at the top having a volume of 32ft^3 and requiring the least amount for its construction.


Given a "rectangular" box, the dimensions of side #1 will match the dimensions of side #3.
Similar for side #2 and side #4.

X = width of sides #1 and #3 of the box
Y = height of the box
Z = width of sides #2 and #4

Then, X times Y times Z is 32.

Area of side #1: X times Y
Area of side #3: X times Y
Area of side #2: Z times Y
Area of side #4: Z times Y
Area of bottom: X times Z

So, minimize: 2 * X * Y + 2 * Z * Y + X * Z

subject to: X > 0 and Y > 0 and Z > 0
and X < 33 and Y < 33 and Z < 33

Or, if you restrict X and Y and Z to be integer-valued, you can "brute-force" it,
i.e., try all combinations:

X Y Z MATERIAL_USED

1 1 32 98
1 2 16 84
1 4 8 80
1 8 4 84
1 16 2 98
1 32 1 129
2 1 16 68
2 2 8 56
2 4 4 56
2 8 2 68
2 16 1 98
4 1 8 56
4 2 4 48
4 4 2 56
4 8 1 84
8 1 4 56
8 2 2 56
8 4 1 80
16 1 2 68
16 2 1 84
32 1 1 98

So, '56' is the MINIMUM value:

2 2 8 56
8 2 2 56
2 4 4 56
4 1 8 56
8 1 4 56
4 4 2 56

How to you factor trinomials


The short story is that this calculator does have a computer algebra system or CAS and thus cannot factor polynomials with arbitrary (unknown) coefficients or known coefficients.
However if the coefficients are given you can ,if you are willing to travel that way, factor approximately a polynomial P(x).
Basically, the idea is that any polynomial P(X) of degree n can be written in the factored form (X-x_1)(X-x_2)...(X-x_n), where x_1, x_2, x_3,...x_n are the roots (real or complex) of the equation P(X)=0.


The procedure ( for a 3rd degree polynomial) is as follows:
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

X^3 (b/a)X^2 (c/a)X (d/a)=0.

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.

How to factor a polynomial equation on casio fx-300es?


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

X^3+(b/a)X^2+(c/a)X+(d/a)=0.

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

Hope it helps.
