Question

Ques. 16) Expand and evaluate the following, using suitable identities.
Expand: (a? + b?)?
Evaluate: 104 x 97​

Answer 1

Answer:

Step-by-step explanation:

i) A binomial is an algebraic expression which has exactly two terms, for example, a ± b. Its power is indicated by a superscript. For example, (a ± b)2 is a power of the binomial a ± b, the index being 2.

ii) (100+4)(100-3)

(X+a)(X+b)=x^2+(a+b)X+ab

=100^2+(1)100+(-12)

=10000+100-12
