Answer:
Step-by-step explanation:
The goal to solving any equation is to have x = {something}. That means we need to get the x out from underneath that radical. It's a square root, so we can "undo" it by squaring. Square both sides because this is an equation. Squaring both sides gives you
Get everything on one side of the equals sign and set the quadratic equal to 0:
Throw this into the quadratic formula to get that the solutions are x = 5 and -8. We need to see if only one works, both work, or neither work in the original equation.
Does ?
and
and 5 = 5. So 5 works. Let's try -8 now:
and
so
-8 = 8? No it doesn't. So only 5 works. Your choice is the third one down.
Answer:
⇒ [Factorized form]
Step-by-step explanation:
Given expression:
We need to make the subject.
In order to do that we need to solve the expression for in terms of
and
We have,
Subtracting both sides by
Taking square root both sides in order to remove square of
The difference of squares can be factorized and written as:
