please tell me Wright Ans​

Answer 1

To evaluate:-

• 106 × 96 using identity

Solution:-

We know the algebraic identity:-

★ (x + y)(x - y) = x² - y²

We have,

= [106 × 96]

= (100 + 6)(100 - 6)

= (100)² - (6)²

= 10000 - 64

= 9984

Therefore, we gets value of 106 × 96 using algebraic identity.

• Expand the numbers

$\sf\implies\red {(100 + 4)(100 - 4 )}$

• here we can seee the identity

$\sf{\bold{\green{\boxed{(a+b)(a-b) = a^2 - b^2}}}}$

$\sf\implies\red{ 100^2 - 4^2}$

$\sf\implies \red {10000 - 16}$

$\sf\implies \red {9984}$

$\sf\implies{\bold{\blue{\boxed{\dag 9986}}}}$

• $\sf (a + b) ^2 = a^2 + b^2 + 2ab$
• $\sf (a - b)^2 = a^2 + b^2 - 2ab$
