Answer:
Roots is a fancy word for zero, which is also another fancy word for the x intercept.
You can factor a quad or use the quadratic equation to get zeros.
In this case, its non-factorable. So you gotta use the quadratic.
Using the quadratic equation you get : x = -2 ± √-1 (√5),
which can be rewritten as x = -2 ± i(√5)
Function was : x^2 + 4x + 9
For quad, I identified the following:
A = 1
B = 4
C = 9
I also added a picture of the formula in the attached.

Answer:
False
Step-by-step explanation:
The way you add 4 digit numbers is by taking each place value and adding them each together. One's get added with ones, tens get added with tens and so on. For example, to add 1864+7528, you would first start off with adding 4 and 8 which gives you 12. The 2 will go under the equation and the 1 will travel to the tens place. Next, 2+6 which is 8 and then add the 1 from 12 which gives you 9. Then, 8+5 which is 13. Again, the 3 will go under the equation and the 1 will travel to the thousands place. Finally, 7+1 which is 8 and then add the 1 from 13 which gives you 9. The sum should be 9392.
