Answer:
If a number is a multiple of 2, it may NOT be a multiple of 4. An example would be the number 6.
, but 
.
However, if a number is multiple of 4, it is guaranteed to be a multiple of 2, since 4 itself is a multiple of 2.
Example:
This is simply
.
It is a multiple of 2 twice.
<span>-2x^2-x+7=0
Variable with the highest degree's (exponent) constant, -2 is a, next variable's constant, -1 is b, the constant or number without a variable, 7 is c
using substitution put the numbers into the formula
</span>(-b±√(b^(2)-4ac))/(a^(2))
(-(-1)±√((-1)^(2)-4(-2)(7))/((-2)^(2)) simplify
(1±√(1+56))/4
1±√(57)/4 is your answer
Option A
x+8=-3
x+8-8=-3-8
x=-11
Hope I didn't mess up for your sake!
I am sure that this problem cannot be solved.
