x ^ 2 - 18 = 0
For this case, the first thing you should do is rewrite the expression:
x ^ 2 - 18 = 0
x ^ 2 = 18
The solutions for this case are:
x1 = root (18)
x2 = -raiz (18)
Therefore the answer is:
2 solutions of real numbers.
Answer:
2
Answer:
or 
Step-by-step explanation:
The given absolute value inequality is 
Divide both sides of the inequality by -2 and reverse the inequality sign:

By the definition of the absolute value function;
Either
or 
Divide through the rightmost inequality by -1 and reverse the sign.
This implies that:
or 
I think yes due to root 2 maybe I am wrong sorry id this was not helpful
