In numerical analysis finding the roots of an equation requires taking an equation set to 0 and using iteration techniques to get a value for x that solves the equation. The best method to find roots of polynomials is the Newton-Raphson method, please look at the related question for how it works.
Rational zero test cannot be used to find irrational roots as well as rational roots.

people i am stuck in the square roots. Can you help by giving me the steps.
One can find more information on grass roots by reading the Plants Today magazine. They go into great detail about certain plants such as grass roots.
MATLAB can be used to find the roots of a given equation by using the built-in functions like "roots" or "fzero". These functions can solve equations numerically and provide the values of the roots. By inputting the equation into MATLAB and using these functions, the roots can be easily calculated and displayed.
To find the roots of a function in MATLAB, you can use the "roots" function for polynomials or the "fzero" function for general functions. The "roots" function calculates the roots of a polynomial, while the "fzero" function finds the root of a general function by iteratively narrowing down the root within a specified interval.
for an 2nd order the roots are : [-b+-sqrt(b^2-4ac)]/2a
z5 is an expression, not an equation and so cannot have roots.

If the quadratic is ax2 + bx + c = 0 then the product of the roots is c/a.
