Answer 1

Answer:

a) 98 x 103 =(100-2) x(100+3) =10094

b)$52^2-48^2=400$

Step-by-step explanation:

a) 98 x 103 =(100-2) x(100+3)

using $(x+a)(x-b)=x^2+x(a-b)-ab$

here x =100, a=3, b=-2

$100^2+100(3-2)-3\times 2\\=10000+100-6\\=10094$

b)

$52^2-48^2\\a^2-b^2=(a-b)(a+b)$

here a= 52 , b=48

$52^2-48^2= (52-48)(52+48)\\=4(100)\\=400$
