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
:


The positive value of
will result in exactly one real root is approximately 0.028.
X=$7 | 1 Ticket= x | 1 Ticket = $7
Answer:
A and B are both 3.
Step-by-step explanation:
The given polynomial is
.
We factor the GCF to obtain:

We factor further by grouping to get:
![3x[x^2(x-6)+3(x-6)]](https://tex.z-dn.net/?f=3x%5Bx%5E2%28x-6%29%2B3%28x-6%29%5D)

We compare this to the given factored expression:

We must have A=3,B=3, C=-6
