The answer is every long.
Step-by-step explanation:
as the figure shows
Using the quadratic equation we get:

Factoring out 2 we get

Factoring out the imaginary number:

So b.
I guess this is what you mean 3√a^10 and 3√b^7
Answer:

Step-by-step explanation:
we are given equation as

Since, we have to solve it by using complete square
so, firstly we will complete square
and then we can solve for x
step-1:
Factor 2 from both sides

step-2:
Simplify it

step-3:
Add both sides 3^2

now, we can complete square

step-4:
Take sqrt both sides

step-5:
Add both sides by 3
we get
