How do you get an equation from its root?
Root is nothing but the value of the variable that we find in the equation.To get a equation from its roots, first we have to convert the roots as factors. By multiplying those factors we will get the required polynomial. 2 and 3 are the roots of the polynomial then we have to write them as The product of those factors will give the polynomial.
Which is the root of a polynomial function?

Can a polynomial be written in factored form?
Polynomials can also be written in factored form () = (− 1)(− 2)…(−) (∈ ℝ) Given a list of “zeros”, it is possible to find a polynomial function that has these specific zeros. In fact, there are multiple polynomials that will work. In order to determine an exact polynomial, the “zeros” and a point
