Hope this helps!
Answer:
D, E
Step-by-step explanation:
(4x - 1) ^2 = 11 => (take square roots of both sides)
4x - 1 = +\- sqrt(11) => (Add 1 to both sides)
4x - 1 + 1 = 1 +\-sqrt(11) =>
4x + 0 = 1 +\- sqrt(11) => (Divide both sides by 4)
x = ( 1 +\- sqrt(11) ) /4
Which are choices D and E

The product of two even numbers is even.
Let m and n be any integers so that 2m and 2k are two even numbers.
The product is 2m(2k) = 2(2mk), which is even.
Things to think about:
Why didn’t I just show you by using any two even numbers like the number 4 and the number 26?
Why did I change from "m" to "k" ? Are they really different numbers or could they be the same?
Why did I specifically say that m and k were integers?
The product of two odd numbers is an odd number.
Let m and k be any integers. This means that 2m+1 and 2k+1 are odd numbers.
The product is 4mk + 2m + 2k + 1 (hint: I used FOIL) which can be written as
2 ( 2mk + m + k ) + 1 which is an odd number.
