Theorems in Algebra

  • Remainder Theorem: For polynomial ( f(x) ) divided by ( x-k ), remainder equals ( f(k) ).
  • Factor Theorem: If ( f(k) = 0 ), then ( (x-k) ) is a factor of ( f(x) ).
  • Rational Zeros Theorem: For polynomial ( ax^n + a_{n-1} x^{n-1} + \ldots + a_1 x + a_0 ), potential rational zeros are given by the ratio of factors of ( a_0 ) to factors of ( a_n ).
  • Fundamental Theorem of Algebra: An ( n )-degree polynomial has ( n ) complex zeros.
  • Linear Factorization Theorem: An ( n )-degree polynomial can be expressed as ( n ) linear binomials of the form ( (x-z) ).
  • Complex Conjugate Theorem: Non-real zeros of polynomials with real coefficients appear in conjugate pairs.
  • Upper Bound Theorem: If ( K > 0 ) and the synthetic division yields all positive coefficients, then ( K ) is an upper bound for the real zeros.
  • Lower Bound Theorem: If ( K < 0 ) and the synthetic division yields alternating coefficients, then ( K ) is a lower bound for real zeros.

Sequences

  • Explicit Formula for Geometric Sequence: ( T_n = T_1 \cdot r^{(n-1)} )
  • Explicit Formula for Arithmetic Sequence: ( A_n = A_1 + D(n-1) )
