Helppp!! ):

Answer 1

t = 0, t = - 2

Explanation:

Given

- t² - 2t = 0 ← factor out t from each term

t(- t - 2) = 0 ← in standard form

Equate each factor to zero and solve for t

t = 0

- t - 2 = 0 ( add 2 to both sides )

- t = 2 ( multiply both sides by - 1 )

t = - 2, thus

solutions are t= 0, t = - 2
