Answer:
Option B , D and E are correct.
Step-by-step explanation:
We set the denominator equal to zero to find the number to put in division box
So, if 3 is in the division box then the denominator will be
x-3 = 0 => x=3 is the root.
So, Option E is correct
2x^2-2x-12 ÷ x-3 = 2x+4 is correct.
because after division the result given is 2x+4 which is correct.
So, Option B is correct
x-3 is a factor of 2x^2-2x-12 because because when the term is divided we get the remainder 0.
So, Option D is correct
So, Option B,D and E are correct.

Answer:
Step-by-step explanation:
The union of two sets P and Q, denoted as 
is the set of all elements that are in the set P or in the set Q or in both sets P and Q.
Given:
P = {7, 8, 9, 10, 11}
Q = {1, 2, 3, 4, 5}
Then
When writing the union set, simply write all elements from both sets in on set.
The denominator is in the bottom of a fraction bar while the numerator is on the top.
