Roots of polynomials. Polynomial roots, or zeros, are the values for which the polynomial equates to zero. These outcomes are obtained by setting the polynomial equal to zero and solving for x. The degree of a polynomial indicates the highest power of x in it. It defines the maximum number of real roots the polynomial can have.

Lemma A.16.1 A very useful trick. If r or − r is an integer root of a polynomial P(x) = anxn + ⋯ + a1x + a0 with integer coefficients, then r is a factor of the constant term a0. Proof. Let us put this observation to work. Example A.16.2 Integer roots of x3 − x2 + 2. Find the integer roots of P(x) = x3 − x2 + 2.

Introduction. (I've written this topic specifically for students taking MEI FP1.) Observe that any quadratic equation can be written in the following form. (x − α)(x − β) = 0 ( x − α) ( x − β) = 0. Where α α and β β are the quadratic's roots. Multiply out the left hand side and you get. x2 − (α + β)x + αβ = 0 x 2 − ( α.
