Question

150×98 by using identity !!

Answer 1

Hey !!!

_____________________________

We Know The Formula (Identity) : (x+a) (x+b) = $x^{2}$ + x (a+b) +ab

We can write, 150*98 as,

(50+100) (50+48) 

Which is Clearly in Form of (x+a) (x+b)

 Hence, Here, 

x = 50

a = 100

b = 48

Acc. To Formula, 

 $x^{2}$ + x (a+b) +ab

$50^{2}$ + 50 (100+48) + 100*48

2500 + 7400+ 4800

9900+4800

14700

Verification: 150*98 = 14700

Hence, Proved
