(2t-2)/(1-t)=-22t−21−t=−2

Explanation:

Observe that when we take 22 common from numerator, we are left with t-1t−1, which is exactly negative of denominator i.e. denominator is (-1)(t-1)(−1)(t−1). Hence using this

(2t-2)/(1-t)2t−21−t

= (2(t-1))/((-1)(1-t))2(t−1)(−1)(1−t)

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

= 2/-1=-2
