Question

t² - 1/t-1
= 2, what value(s) may 't have?

Answer 1

Answer:t^2-1/t-1=2

t^2-1^2/t-1

(t+1) (t-1)/(t-1)=2

t+1=2

T=1

Step-by-step explanation:

Answer 2

Answer:

t can not have any value

Step-by-step explanation:

t² - 1/t  -1 = 2

=>  ( t² - 1)/(t - 1) = 2

=>  t² - 1 = 2t - 2

=> t² - 2t + 1 = 0

=> t² - t - t + 1 =0

=> t(t - 1) - 1(t - 1) =0

=> (t - 1)² = 0

=> t = 1

then t - 1 = 0  but t- 1 ≠ 0 because its in denominator

Hence t can not have any value
