Answer:
Step-by-step explanation: when you are multiplying an equation how do you find like terms The ones that look alike. The numbers are like terms such as 4 or 8 or 10. The variables are like terms such as 4x or 9x or 3x but both of these like terms are different still from say 4x^2
when you are multiplying an equation how do you find like terms
The ones that look alike. The numbers are like terms such as 4 or 8 or 10. The variables are like terms such as 4x or 9x or 3x but both of these like terms are different still from say 4x^2 or 19x^3. Another way to look at it that numbers are one kind of like terms, all of the xs will be like terms, all of the ys will be like terms, all of the x^2 values will be alike, etc. I hope this helps.
like terms are the same like 3x and 8x are like, 8x^2 and 3x are not. the "X" must match and the power must match.

Step-by-step explanation:
a) f(x) > 0 for all x: (-∞, ∞)
__
b) f(x) > 4 for x < 3 and x > 5: (-∞, 3) ∪ (5, ∞)
__
c) f(x) < 5 for 2 < x < 6: (2, 6)
_____
<em>Comment on the notation</em>
The brackets are round brackets (parentheses) because the end points are not included in the interval. The first number corresponds to the left end of the interval on the number line. The second number corresponds to the right end of the interval on the number line. When intervals are disjoint, their union is indicated with the appropriate symbol.
If the end number is included in the interval, a square bracket is used:
1 < x ≤ 3 ⇒ (1, 3]
