(4a-3b+11c) (a+b) - (16b-13c+12a)(a-c)
4a²-3b²+11c - (16b+13c²+12a²)
4a²-3b²+11c -16b -13c²-12a²
4a²-12a²-3b²-16b-13c²+11c
-8a²-3b²-16b-13c²+11c
∴THE SIMPLIFIED FORM IS
-8a²-3b²-13c²-16b+11c
HOPE IT HELPS

Step-by-step explanation:
=(4a-3b+11c)(a+b)-(16b-13c+12a)(a-c)
=(4a-3b+11c×a)+(4a-3b+11c×b)-(16b-13c+12a×a)-
(16b-13c+12a×c)
=4a^2-3ab+11ac+4ab-3b^2+11bc-16ba+13ac+12a^2
16bc+13c^2-12ac
=4a^2-12a^2-3b^2+13c^2-3ab+4ab-16ab-12ac
-16bc
=-8a^2-3b^2+13c^2-15ab-12ac-16bc
