Elementary Algebra Answer 1
Elementary Algebra Answer 1:
1. How many solutions exist for the following equation:
x2 + 8 = 0
a. 0
B. 1
C. 2
D. 4
E. 8
The correct answer is A.
REMEMBER: Any real number squared will always equal a positive number.
Since 8 is added to the first value x2, the result will always be 8 or greater.
In other words, since x2 is always a positive number, the result of the equation would never be 0.
So there are zero solutions for the equation.
