Answer:
Step-by-step explanation:
We want to convert the interval [-1, ∞) to inequality notation using <em>x</em> as the variable.
The interval [-1, ∞) reads: "All real numbers between -1 and positive infinity."
In other words, it is all numbers greater than or equal to -1 and less than positive infinity.
Therefore:
Note that we do not use "or equal to" for the infinity as we can never really "equal" infinity.
Answer:
Yes
Step-by-step explanation:
Yes it is possible to solve a quadratic equation that is not factorable over the set of integers.
The solution may vary like Integers, rationals, irrationals or complex solutions.
To find two roots of the equation we can always use the formula given below to solve a quadratic equation,
For the quadratic equation,
, we have,
If the discriminant is greater than , we get complex roots.
