Answer 2

⚝ SOLUTION ⚝

➣ 105×94

➣ (100+5)*(100-6)

Using identity = (x+a)(x+b)

⍟ We Know That :-

The first term of the both sum basis binomials is same and it is a special case in algebraic mathematics. Therefore, the product of special binomials is called as the special product of binomials or special binomial product.

➣ x² + (a+b)x+ab

➣100² +(5+(-6))100 + (5*-6)

➣ 10000+(5-6)100+(-30)

➣ 10000 -100 -30

➣ 9900-30

➣ 9870
