Sorry, but you cannot use this calculator to factor a general polynomial.
1. It does not know symbolic algebra.
2. It can only manipulate numbers.

However if you have polynomials of degree 2 or 3, with numerical coefficients (no letters) you can set [MODE] to Equation and use the equation solver to find the real roots of 2nd degree or 3rd degree polynomials. Assuming that your polynomials have real roots (X1, X2) for the polynomial of degree 2, or (X1, X2, X3) for the polynomial of degree 3, then it is possible to write

P2(X) =a*(X-X1)(X-X2)
P3(X)= a(X-X1)(X-X2)(X-X3)

where a is the coefficient of the highest degree monomial aX^2 +...
or aX^3 +....

This is an approximate factorization, except if your calculator configured in MathIO, has been able to find exact roots (fractions and radicals)

While the [MODE][5:Equation] only handles quadratic and cubic equations, the [SHIFT][SOLVE=] solver finds the roots of arbitarry expressions (not limited to polynomials). In principle you can use it to find the roots of an expression. If it is a polynomial of dgree higher that 3 you can factor it (approximately).

But I have a hunch that this is not what you wanted to hear.

Hope it helps.

What is least common factor

Normally, we look for the greatest common factor and the least common multiple.

To find the least common factor, we have to factor both numbers and see what the least common factor is. However, we know the one set of factors for every number is itself and one. For example, 56 and 49.

The factors of 56 are 1, 2, 4, 7, 8, 14, 28 and 56.
The factors of 49 are 1, 7, 49.

What is the least common factor of both numbers? 1

So the least common factor of any two numbers is 1.

Any questions, let me know.

Good luck,

How do I get all the factors of a constant using my calculator?

There is a program on page 253 of the manual ( to get the prime factors of any number. You could modify the program to get all the factors.

Another way would be to do it manually. I start with the number 1 and go up to the square root of the number. The square root of 120 is 10.95, so let's go up to 11. Using 120 as an example:

120 /1 = 120 thus factor is (1, 120)
120/2 = 60 thus factor is (2, 60)
120/3 = 40 thus factor is (3, 40)
120/4 = 30 thus factor is (4, 30)
120/5 = 24 thus factor is (5, 24)
120/6 = 20 thus factor is (6, 20)
120/7 = 1.7 thus 7 not a factor
120/8 = 15 thus factor is (8,15)
120/9 = 13.3 thus 9 is not a factor
120/10 = 12 thus factor is (10,12)
120/11 = 10.9 thus 11 is not a factor.

Good luck.

How much horsepower does my intex Crystal Clear Model 635T filter pump have? I'm looking at a hth vacuum that requires at least 1/2 horse power. thanks

If the unit does not have the horsepower rating, but has the AMP rating, try this formula found in

"Amps are a factor in calculating power, and so can be used to determine horsepower, but only when other factors are present.
Given other factors, you can find the horsepower. The easiest way is to determine watts by multiplying amps X volts. Next multiply watts by .00134 and you have horsepower.
If: amps (A)= 20 and volts (V)=120 then
A X V =2400 watts (W)
2400 watts X .00134 = 3.216 horsepower"

Hope this helps you???

How can I find out what the Energy Rating is on my Reliance 501 w/h?

Reliance is AO Smith company.

1) Reliance does not post the 501 manual any more and I've written and asked for that manual, and they sent generic manual. Model 501 is both gas and electric.

2) That tells me the old energy factor is probably lower than .54 approximately, but it will be even less because energy factors are for new water heaters in perfect operating order under ideal conditions.

3) Energy factor is a measure of how efficiently the water heater turns energy BTUs into hot water.
Gas water heaters have higher energy factor because gas burner has more BTU punch than electric element, and can heat water faster.

4) However, energy factor is not measure of actual cost. It is merely a way to compare giant water heaters with smaller heaters, and gas with electric, without considering cost of heater, installation cost, repair costs, parts costs, life expectation of unit, disposal/recycling cost, or replacement cost.

5) You can improve your true energy factor by buying small cheap heater and maintaining it yourself so it lasts many years beyond manufacturer's warranty.

6) If someone buys a bigger water heater because it has better energy factor, it will not pay back the higher purchase cost. Same size to same size, the difference with higher energy factor is a few dollars per year.

7) If you have sediment inside of tank, the energy factor is out the window.
