i tried -8 and it was wrong...

here’s my work.... i am going to make my work neater next time😐

Maybe you can just point out the mistake I made only...

x * y = ( x + 2) ( y - 3)

So

t * ( t + 2) =

(t + 2) * [(t + 2) - 3 ] =

( t + 2) ( t - 1)

t^2 + t - 2 (1)

And

(t + 1) ( t + 1) =

[ ( t + 1) + 2 ] * [ ( t + 1) - 3 ] =

( t + 3) ( t - 2) =

t^2 + t - 6 (2)

(1) - (2) =

[ t^2 + t - 2 ] - [ t^2 + t - 6 ] =

4

I got it right the first time!!! :( I got -8 when I went back and check my work... I guess I should never go back and check my work again?
