Algebra problem: making "y" the subject. -8(y-1)² = t

The actual Question is:- Rearrange the following equation to make y the subject. t = -8 (y-1)². I presume this part of the equation has to be calculated first (y-1)², in order to get rid of the parentheses.

If you'd been given "-8y = t" and asked to solve for "y=", what would you have done?

If you'd been given "y2 = t" and asked to solve for "y=", what would you have done?

What happened when you applied the above techniques to the posted exercise?

Please be complete. Thank you! ;)
