Cubic function with one zero
WebThe two known roots have sum 2, so the missing root must be − 2. If the leading term of the polynomial has coefficient 1, then the product of its roots gives the free term. Your polynomial has real coefficients; if 1 − 2 i is a root, then so is 1 + 2 i. Thus, we arrive to 10 = ( 1 − 2 i) ( 1 + 2 i) a, where a is the real root. WebNov 24, 2016 · Explanation: Multiply together linear factors with each of these zeros: f (x) = (x +3)(x − 2)(x − 1) = x3 − 7x + 6. Any polynomial in x with these zeros will be a multiple …
