Question

How do you simplify `(2t-2)/(1-t)`?

Answer 1

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

Explanation:

Observe that when we take `2` common from numerator, we are left with `t-1`, which is exactly negative of denominator i.e. denominator is `(-1)(t-1)`. Hence using this

`(2t-2)/(1-t)`

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

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

= `2/-1=-2`
