Fundamental of Mathematics – II Fundamental of Mathematics – II 1. Remainder Theorem of Polynomial 1.1 Zeroes of a Polynomial A number a is called a zero (or root) of the polynomial p(x) if p(a) = 0 . Zeroes give insights into the behavior and factorization of polynomials. Practice Questions Find the zeroes of p(x) = x² – 5x + 6 . Show Answer Solve x² – 5x + 6 = 0 ⇒ (x – 2)(x – 3) = 0 ⇒ x = 2, 3. 1.2 Roots of an Equation The roots of the equation p(x) = 0 coincide with the zeroes of the polynomial. Solving the polynomial equation yields its roots, which may be real or complex. Practice Questions Determine the roots of x³ – 2x² – x + 2 = 0 . Show Answer By grouping: x²(x–2) –1(x–2) = (x–2)(x²–1) ⇒ (x–2)(x–1)(x+1)=0 ⇒ x=2,1,−1. 1.3 Factors of a Polynomial If ...
