Step wise Equation Solving
I was writing a program to obtain the results of a linear quadratic equation and i used the jhplot.math.Numeric class to compute the results. I was wondering if i could

a) solve quadratic equation in a step by step fashion storing intermediate results.

for example :
x2-4x+3=0
x2-3x-x+3=0
x(x-3)-1(x-3)=0
(x-1)(x-3)=0
x=1 and x=3

b) plot the quadratic equation as a graph in 2d space.

I am using the data melt one jar file to write the program in java and am a newbie.

Any help in this regard would be much appreciated.

thanks.

RE: Step wise Equation Solving
Hello,

I'm not sure about intermediate steps, but to solve and

Code:
```from jhplot.math.Numeric import * b=solveQuadratic(1, 2, -1) #a=1, b=2, c=-1 print b.tolist() from jhplot import * c=HPlot() c.visible() c.setAutoRange() f=F1D("x**2+2*x-1",-5,5) c.draw(f)```

Also, check Apache common math included into the package

best, Sergei
