The factorial of n, or n! is the product of all positive integer numbers from 1 to n. The value n! is called "n factorial" and is calculated by following formula: n! = n × (n - 1) × (n - 2) × . . . × 1 , n > 0. By convention, 0! = 1. For example, the factorial of 7 is equal to 7×6×5×4×3×2×1 = 5040.
To factor a trinomial x^2+bx+c find two numbers u, v that multiply to give c and add to b. Rewrite the trinomial as the product of two binomials (x-u)(x-v)
