SOURCE: how to solve quadratic equation in SHARP EL-531WH

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.

Hi there,

You cannot solve linear equations on a SHARP EL531. If you would like a calculator that solves equations, you need to get a SHARP EL W506

Hello,

The [2ndF] key allows access to other functions. I do not have the calculator under my nose, but I suspect under the [2ndF][LOG] you access the 10 to the power x function [10^x] or [10 to the x].

Hope it helps.
