Question

2.
Using (h + a) (h + b) = h2 + (a + b) h + ab, find 98×103​

Answer 1

Step-by-step explanation:

103 × 98 = (100 + 3) (100 − 2)

= (100)2 + [3 + (− 2)] (100) + (3) (− 2)

= 10000 + 100 − 6

= 10094

Answer 2

Answer:

answer=10094

Step-by-step explanation:

98x103

formula given is

(h+a)(h+b)=h²+(a+b)h+ab

using this, substitute the values

(100+(-2)) (100+3)=(100)²+(3+(-2)) x100+3(-2)

=10000+100-6

=10000+94

=10094
