观察例题→发现规律→按照要求答题. (120×120)-(119×121)=1,(120×120)-(118×122)=4, (120×120)-(117×123)=9,(120×120)-(116×124)=16, … (1)(120×1

问题描述:

观察例题→发现规律→按照要求答题.
(120×120)-(119×121)=1,(120×120)-(118×122)=4,
(120×120)-(117×123)=9,(120×120)-(116×124)=16,

(1)(120×120)-(112×128)=______.
(2)(120×120)-(______×______)=144.

(120-112)×(128-120)=8×8=64;
12×12=144,
120-12=108,
120+12=132,
120×120-108×132=144;
故答案为:64,108,132.
