Is this how you prime factorize? And is that the correct answer?
1 answer:
You have the correct factor tree drawn out. Nice work on that. However, the final answer is not choice D.
The answer is actually choice C)
Notice how there are two '3's in the tree. One is below the 6 and the other is below the 126. So we really have 2*3*3*5*7 which turns into 2*3^2*5*7 which is what choice C is saying.
Note: 2*3^2*5*7 is the same as

Answer:
The positive value of will result in exactly one real root is approximately 0.028.
Step-by-step explanation:
Let , roots are those values of
so that
. That is:
(1)
Roots are determined analytically by the Quadratic Formula:
The smaller root is , and the larger root is
.
has one real root when
. Then, we solve the discriminant for
:
