SOURCE: How do I use sharp EL W531 to solve quadratic

Hello,

This calculator does not have a program to which you give the
equation, and which returns the solutions. Sorry. You have to use the
formulas you learned.

Let the equation be ax^2 +bx+c=0

You compute the discriminant Call it disc.**disc= (b^2-4*a*c)**

1. If discriminant is larger than zero you have two solutions. Let us call them x1 and x2.

Then** x1=(-b+square root of disc)/(2*a)**

and **x2= (-b-square root of disc)/(2*a)**

2.** If disc=0** , square root of disc =0 and** x1=x2=-b/(2*a)**

3. **If disc is negative, there are no real solutions.**

To find the solutions you **replace a, b, and c **by their numerical values, to calculate disc, its square root, and calculate X1 and X2.

Hope it helps.

From the manual:**SETTING THE NUMBER OF DECIMAL DIGITS**

Numbers of decimal digits of calculation results can be specified by pressing [C-CE] twice, then press [C-CE]and [M+] simultaneously.

The decimal digit assignment will appear as “F” (for “floating point”), “2” or “0” on the LCD. (The default is “F”.)

Press and hold [C-CE] and [M+] until the symbol changes.

Up Arrow: Answer is rounded up

5/4 key: Answer is rounded off

Down arrow: Answer is rounded down

The decimal will float if the calculation is multiplication or division

If the decimal selector is set to F then the answer is always rounded down

5/4 key: Answer is rounded off

Down arrow: Answer is rounded down

The decimal will float if the calculation is multiplication or division

<span><b>Getting Decimal Answers by Disabling WriteView<img src="elw516.gif" /> on the Sharp EL-W516 Calculator<br /><br /></b>The Sharp EL-W516's WriteView display uses multiple lines to display mathematics as it is seen on a page. Fractions are shown as fractions, exponents as exponents, integrals as integrals, and so on. This makes entering calculations easier, and reduces the chance of errors. <br /><br />At the same time, calculation results are displayed as fractions (or with roots or pi) whenever possible. Pressing the CHANGE button repeatedly will change these to decimal answers. <br />If you prefer to always get decimal results you need to <b>disable</b> <b>the WriteView display mode</b>. Doing this will make the calculator display like the Sharp EL-546W when in NORMAL mode. Answers will be given as decimals, but fractions will no longer look like fractions. In general, you will still need to follow the EL-W516 instructions.<br /><b>Disabling WriteView<br /></b><br />Press 2ndF and MATH to enter SET UP. Now press 2 for EDITOR.<br /><br />There are now two options: 0: W-VIEW, and 1: LINE<br /><br />Press 1 for Linear display mode to disable the WriteView display, and to get decimals as your answers.<br /><br />To return to the WriteView display, go through the steps above but press 0 for W-VIEW.<br /><br /><b>NOTE</b>: It is not possible to have decimals as the default answer form when in WriteView mode. <br /></span>

through the following display styles:

• Mixed fractions (with or without ?) ? improper fractions (with

or without ?) ? decimal numbers

• Proper fractions (with or without ?) ? decimal numbers

• Irrational numbers (square roots, fractions made using square

roots) ? decimal numbers

Notes:

• In the following cases, calculation results may be displayed

using r:

• Arithmetic operations and memory calculations

• Trigonometric calculations

• In trigonometric calculations, when

entering values such as those in

the table to the right, results may be
