Roots are zeroes that can go up or down
Web8 Jan 2024 · The Rational Zero Theorem helps us to narrow down the number of possible rational zeros using the ratio of the factors of the constant term and factors of the leading coefficient of the polynomial Consider a quadratic function with two zeros, x = 2 5 and x = 3 4. By the Factor Theorem, these zeros have factors associated with them. Web21 Aug 2016 · “The sum of all primitive roots (of a prime number p) is either ≡ 0 (when p-1 is divisible by a square), or ≡ ±1 (mod p) (when p-1 is the product of unequal prime numbers); if the number of these is even the sign is positive, but if the number is odd, the sign is negative.” The Prime Counting Function Back to primes.
