Answer:
(x+7)(x+1)(x-4)
Step-by-step explanation:
A zero is is the x-intercept of the function. It is also known as the root. From the equation, the zero or root comes from the factors. When the factors are set equal to 0, we solve for x and the zero is the result. We will reverse this by taking the opposite value of the zero and placing into a factor expression. Remember the factor has the form x+a.
-7: x+7
-1: x+1
4: x-4
We write them together. (x+7)(x+1)(x-4). With more information we could find the leading coefficient and so forth.
