Easy. a^2 - b^2 = (a+b)x(a-b) => (1998+1997)x1 =3'995

1998²-1997²=? a²-b²=(a+b)(a-b) (1998+1997)(1998-1997) =3995x1= 3️⃣9️⃣9️⃣5️⃣

1998² − 1997² = (1998 − 1997)(1998 + 1997) = (1)(3995) = 3995

or. 1998^2-1997^2=(1998-1997)(1998+1997) . let x=1998. (x-(x-1))(x+x-1)= (x-x+1)(2x-1)= 1(2x-1)=2x-1=3995

Chụp hình phong cảnh :
1998^2-1997^2=(1998+1997)(1998-1997)=(1998+2-1995)*1=3995

Moon knight :
The general fórmula for this case is 2a-1, Where a is 1998. Expl.: make a = 1998 and a-1=1997. Another way is (1998-1997)(1998+1997)
