can there be a square root in a polynomial function It is a polynomial if the square root is in a coefficient but not if it is applied to the variable A polynomial can have only integer powers of the variable Thus sqrt 2 x3 4 x 3
The nth root of a number a sqrt large n a a 1 n The square root of the square root of x is therefore sqrt sqrt x sqrt x 1 2 x 1 2 1 2 x 1 4 sqrt large 4 x Since the domain of sqrt x is In particular for an expression to be a polynomial term it must contain no square roots of variables no fractional or negative powers on the variables and no variables in the denominators of any fractions

Here is a way Let the square root be x2 ax 2b You want to know the coefficient of the x term and you know the constant will be either be 2 or 2 Square this Square root of polynomial The f f denoted by f f is any polynomial g g having the square g2 g 2 equal to f f For example 9x2 30x 25 3x 5 9 x 2 30 x 25 3 x 5 or
If such phi exists it does in this example phi can be viewed as a square root of f in the sense of function composition because phi circ phi f Is there a general In order to find the square root of the polynomial first arrange the terms with reference to the power of the same numbers Then took the square root of the first term of the polynomial for

A polynomial function is a function that involves only non negative integer powers or only positive integer exponents of a variable in an equation like the quadratic equation cubic equation etc For example 2x 5 is a polynomial that has Can A Rational Function Have A Square Root A rational function cannot have a square root in the numerator or denominator The reason is the definition of a rational function it is a quotient of polynomial functions For a rational function
In this section you will learn how to find square root of a polynomial using long division Before learning learn how to find square root of a polynomial you are advised to look at the stuff There are two possible values for x to solve the polynomial Since there is a square root of a negative number involved the results are complex numbers
