A quadratic function has zeros -7 and 9. What are the linear factors of the function? (x-7)(x+9)
0 (x-7)(x-9)
X+7)(x+9)
0 (x+7) (X-9)

(x+7)(x-9) = 0

Step-by-step explanation:

x + 7 = 0

x = -7

x - 9 = 0

x = 9

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
