First of all, we can observe that

So the expression becomes

This means that the expression is defined for every 
Now, since the denominator is always positive (when it exists), the fraction can only be positive if the denominator is also positive: we must ask

Since we can't accept 3 as an answer, the actual solution set is
![(-\infty,-2] \cup [2,3) \cup (3,\infty)](https://tex.z-dn.net/?f=%28-%5Cinfty%2C-2%5D%20%5Ccup%20%5B2%2C3%29%20%5Ccup%20%283%2C%5Cinfty%29)
Answer:
720$
Step-by-step explanation:
(1000+(230*24))-5800=720
Answer:
x=-2
Step-by-step explanation:
If x always = -2, it is a straight vertical line which means it is parallel to the y axis
J times the product of 4 and 7:
J(4x7)
Answer:
x = ± 
Step-by-step explanation:
Given
ax² + b = c ( subtract b from both sides )
ax² = c - b ( divide both sides by a )
x² =
( take the square root of both sides )
x = ±
