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?
