SOLUTION: find the solution set of square root of (2t+4)= square root of (t-1) and check for extraneous solution if any?

Question 758247: find the solution set of square root of (2t+4)= square root of (t-1) and check for extraneous solution if any?
Answer by tommyt3rd(5050) (Show Source): You can put this solution on YOUR website!

leads to

2t+4=t-1
t=-5
(extraneous unless we allow for imaginary numbers)
or

2t+4=-(t-1)
3t=3
t=1
(extranoous)

We see that over the reals this equation has no solution. Iver the complex numbers, x=-5

:)
