Answer:

Step-by-step explanation:
The given polynomial is

The factors of -6 that sums up to -1 are -3,2.
We split the middle term to obtain:

We factor to get:

We factor further to get:

The polynomial is equivalent to:

We can use quadratic formula to determine the roots of the given quadratic equation.
The quadratic formula is:

b = coefficient of x term = -11
a = coefficient of squared term = 2
c = constant term = 15
Using the values, we get:
So, the correct answer to this question are option B and D
Property of Zero because anything multiplied by 0 equals 0. If this is right could I possibly have brainliest? Hope this helped!! :)
54,273 = A * 1.70^6 where A is the initial number
A = 54273/1.70^6 = 2248
