Answer:
Step-by-step explanation:
Given that :103×98
It can be written as ( 100+3)×(100-2)
=>(100+3)×(100+(-2))
It is in the form of (x+a)(x+b)
Here,
x=100
a=3
b=-2
We know that
(x+a)(x+b)=x²+(a+b)x+ab
=>103×98
=>(100+3)×(100+(-2))
=>(100)²+(3-2)(100)+(3×(-2))
=>10000+100-6
=>10100-6
=>10094
103×98=10,094
