A quadratic with roots at 8 and 5 is f(x) = x^2 +12x + 20
In order to find an equation given roots you can create statements that equal 0 in order to create parenthesis. For instance we know x = 8 at one point. So, we can solve that to equal 0.
x = -2 ----> add 2 to both sides
x + 2 = 0
We can do the same for the other zero.
x = -10 ----> add 10 to both sides
x + 10 = 0
Now that we have both of these, we can multiply these two things together. This will give us the function we need.
f(x) = (x + 2)(x + 10)
f(x) = x^2 + 10x + 2x + 20
f(x) = x^2 + 12x + 20
Answer:
1. d = -6 2. n = -80
Step-by-step explanation:
If you divide 42 by -252 you get -6. And if you use your mental math you see that two negatives make a positive then you see it has to be negative and 80/4= 20 than -80/-4 = 20. Hope this helps, let me know if correct, and have a great day!!
