How do you solve for x using a quadratic equation?
For an equation of the form ax² + bx + c = 0 you can find the values of x that will satisfy the equation using the quadratic equation: x = [-b ± √(b² - 4ac)]/2a
How do you find for the zero of a linear function?
If it is a linear function, it is quite easy to solve the equation explicitly, using standard methods of equation-solving. For example, if you have "y" as a function of "x", you would have to solve the variable for "x".

you cant
How do you solve an equation using division?
Divide big # by little #.
How do you formulate quadratic equation that can be solve by extracting square roots?
By using the quadratic equation formula
How do you solve a equation using unknown variables?
You don't use unknown variables to solve an equation. The purpose of solving an equation is to find the value of the variable so that it's no longer unknown.
How do you solve diophantine equation using python?
To solve a diophantin equation using python, you have to put it into algebraic form. Then you find out if A and B have a common factor. If they have a common factor, then you simplify the equation. You then build a three row table and build the table.
