Web27 de may. de 2024 · By using your factor tree method, you have factored it to 2 × 2 × 19 × 31 × 829. At this point, if you are doing it right (test the divisibility of 5 9 − 1 starting from the smallest prime number, which is 2 ), then the number 829 is not divisible by any prime numbers from 2 to 31. WebWe can see that it simplifies to -2 and -4. Remember, the Quadratic Formula gives you the roots (zeros). These are the values that make the expression equal to 0. We can use the roots to write the factors. If -2 is a root, that means (x +2) is a factor. If you plug … port orchard theaters \u0026 performance venues
