Answer:(t + 3 )(t - 1 )
Step-by-step explanation: From the polynomial or trinomial
t² + 2t - 3 , this is just factorization without calculating the roots, since it is not equated to zero.
Using grouping method of factorization,
t² + 3t - t - 3,
t(t + 3) - ( t + 3),therefore collect like factors, the polynomial expression will be
= (t + 3 )(t - 1 )
