Sya agk sdikt lpa2.
pi mdh2n bsa ya..

L= integral min 3 smpai 2 (x^2+x-2) dx
=1/3 x^3 + 1/2 x^2 - 2x| min 3 smpai 2
=1/3 (2)^3 + 1/2(2)^2 - 2 (2) -{1/3(-3)^3 + 1/2 (-3)^2 - 2 (-3)}
=8/3+2-4 - {(-9) + 9/2 +6}
=8/3-2 - {9/2-3}
=8/3-6/3 - {9/2 - 6/2}
=2/3 - 3/2
=4/6 - 9/6 = |-5/6|=5/6 satuan luas.

nih yg sya ingt. trima ksih..
