2020-05-19 21:17:15 +0200 | asked a question | Find quadratic polynomial such that f(x)=x^2+ax+b is prime a. Find quadratic polynomial f(x)=x²+ax+b , a,b ∈ℤ such that f(x) is prime for 1≤n≤40 I know that the polynomial f(x)=x²-x+41 takes prime values for all 1≤n≤40. But how can I find this polynomial with sage? b. Find k (as large as possible) and quadratic polynomial such that f(x)=x²+ax+b (a,b ∈ℤ) is prime for 1≤n≤k I only find can b if I know a. But how can I find both? |
