What is the solution of

Option A

Step-by-step explanation:

Find zeros first:

x² + x - 6 = x² + 3x - 2x - 6 = x(x + 3) - 2(x + 3) = (x - 2)(x + 3)x = 2, x = -3, x = 7 (but x ≠ 7 as no division by zero)

We have 4 intervals:

x ≤ - 3, three negatives, the result is negative or zero-3 ≤ x ≤ 2, two negatives and one positive, the result is positive or zero2 ≤ x < 7, two positives and one negative, the result is negative or zerox > 7, three positives, the result is positive or zero

The solution is:

x ≤ - 3 or 2 ≤ x < 7

Correct choice is A

31 is prime. and it’s prime factorization is just 31.
