Question

expansion formula
(105)2​

Answer 1

Answer:

In algebra, the algebraic expansion of powers of a binomial is expressed by binomial expansion. In binomial expansion, a polynomial (x + y)n is expanded into a sum involving terms of the form a x + b y + c, where b and c are non-negative integers, and the coefficient a is a positive integer depending on the value of n and b. Let us learn more about the binomial expansion formula.

Step-by-step explanation:

formula us ax+by+c

Answer 2

Answer:

11025

Step-by-step explanation:

We know that,

(a+b)² = a²+b²+2ab

∴ (105)² = (100+5)²

11025 = 100² + 5² + (2×100×5)

11025 = 10000 + 25 + 1000

11025 = 11025

∴LHS = RHS
