How To Find A Polynomial Of Given Degree With Given Complex Zeros Youtube Step 1: for each zero (real or complex), a, of your polynomial, include the factor x − a in your polynomial. step 2: if your zero is a complex number a = c d i, also include the factor x −. 👉 learn how to write the equation of a polynomial when given complex zeros. recall that a polynomial is an expression of the form ax^n bx^(n 1) . . . By the factor theorem, we can write f (x) f (x) as a product of x−c1 x − c 1 and a polynomial quotient. since x−c1 x − c 1 is linear, the polynomial quotient will be of degree three. now we apply the fundamental theorem of algebra to the third degree polynomial quotient. it will have at least one complex zero, call it c2 c 2. Example question #1 : find complex zeros of a polynomial using the fundamental theorem of algebra. the polynomial intersects the x axis at point . find the other two solutions. possible answers: correct answer: explanation: since we know that one of the zeros of this polynomial is 3, we know that one of the factors is .

Finding a polynomial of given degree with given zeros. step 1: starting with the factored form: p (x) = a (x − z 1) (x − z 2) (x − z 3) adjust the number of factors to match the number of. How to: given the zeros of a polynomial function f f and a point \left (c\text {, }f (c)\right) (c, f (c)) on the graph of f f, use the linear factorization theorem to find the polynomial function. use the zeros to construct the linear factors of the polynomial. multiply the linear factors to expand the polynomial.
