"WebJun 12, 2024 · For zeros, we first need to find the factors of the function x^ {2}+x-6 x2 + x − 6. The factors of x^ {2}+x-6 x2 + x − 6 are (x+3) and (x-2). Now we equate these factors with zero and find x. i.e., x+3=0 x + 3 = 0 and x-2=0 x − 2 = 0. i.e., x=-3 x = −3 and x=2 x = 2. In a simple way, x^ {2}+x-6=0 x2 + x − 6 = 0.
