Who can make a quadratic equation calculator using php?

Answer 1

it is server side language, you have to use html to get user input and than use input value like

<textarea name="hello"></textarea>

you can use $_GET['hello'];

you can also use $_POST. Use Shree dhar formula

roor1=(-b+sqrt(b*b-4*a*c))/2*a;

get root2 by changing + into - after -b.
