Let
Then
and solving for x gives
By the quadratic formula,
but x must be a positive number, so only the positive square root solution is valid.
We identify a = c = 3 and b = 2, so a + b + c = 8.
What is larger .9% or 1%??

<h3>How to graph the set on a number line?</h3>The set is given as:
(−∞, 0) ∪ [2, 8]
The above means that the numbers inclusive in the set are:
- (−∞, 0): All real numbers less than 0
- [2, 8]: All real numbers between 2 and 8 (inclusive)
This means that there will be a gap on the number line between 0 and 2 and from 8 till positive infinity
Having done the above illustration, next we plot the set on a number line
