You actually have two zeroes: 2 + 3 i and 2 − 3 i because complex zeros always come in a pair of complex conjugates. Which means, you now have: [ x − ( 2 − 3 i)] [ x − ( 2 + 3 i)] Expand this you get. ( x 2 − 4 x + 13) Then use this as a divisor to your original polynomial. pet food direct

WebUse synthetic division to evaluate a given possible zero by synthetically dividing the candidate into the polynomial. If the remainder is 0, the candidate is a zero. If the remainder is not zero, discard the candidate. … WebA "root" is when y is zero: 2x+1 = 0. Subtract 1 from both sides: 2x = −1. Divide both sides by 2: x = −1/2. And that is the solution: x = −1/2. (You can also see this on the graph) We can also solve Quadratic Polynomials using basic algebra (read that page for an explanation). 2.
