Answer:
d = 3 & d = -3
Step-by-step explanation:
the equation to solve is
Let's remember some properties of numbers and radicals.
Let's take the number 2 for example.
We know
Also
as well
Since negative TIMES negative also gives us positive.
How do we get the reverse answer? Simple. We square root it. So we would have:
and
-2, since we now know this.
Let's do this process and take square root of our equation to get:
and also d = -3
Hence, two values of d are d = 3 & d = -3
