In mathematics, a factor is a number or polynomial that divides another number or polynomial evenly. For example, the factors of 12 are 1, 2, 3, 4, 6, and 12. The zeros of a polynomial are the values of the variable that make the polynomial equal to zero. For example, the zeros of the polynomial x^2 – 4 are -2 and 2.
If you know one or more of the zeros of a polynomial, you can use this information to find the remaining zeros. To do this, you can use a variety of methods, including synthetic division, factoring, and the quadratic formula.
