I'm confused about how to solve this?
Square both sides to undo that radical. :) You are trying to get to the t so undo the things around it.
In order to solve for t u have to isolate t. 1.Square both sides 2.Add 5 to both sides.

okay
Then t = 9
\[\sqrt{t-5} = 2\] \[t-5 = 4\] \[t = ?\]
yup perfect:)
right :)
Now what about one like x = √(56-x)
whenever u have square roots on one side try to remove them by squaring both sides. Can u plz tell me vat u get when u square both sides?
x^2= 56 - x
then would i use quadratic formula
yup right:) good work.:) Nw bring all the terms to one side. Then use quadratic formula to find x. Quadratic formula is \[x=\frac{ -b\pm\sqrt{b^2-4ac} }{ 2a }\]
-8 and 7
x = -8 and 7
yup perfect:) great work:)
Thanks!
welcome:)
