Question

Evaluate without multiplying directly ( + 8)( − 10)​

Answer 1

Answer:

Here is your solution

=> 11021. (ii)95×96. (90 + 5) (90 + 6) by using identity :- (x + a) (x + b) = x² + (a+b)*x + ab. x = 90 , a = 5 , b = 6. Now put value of x , a & b. ...

=> 9120. (iii)104×96. (100 + 4) (100 - 4) by using identity :- (x + a) (x + b) = x² + (a+b)*x + ab. x = 100 , a = 4 , b = (-4) ...

=> 9984.
