​

Answer 1

Answer:

a²-b²=a+b)(a-b)

Step-by-step explanation:

(53+43)(53-43)

96×10

960

Answer 2

Answer :

• 960.

Explanation :

Here, we are given with an expression and we have to find its value with a suitable identity.

So, Let's Begin.

➙ 53² - 43²

Use Identity :- (a² - b²) = (a + b)(a - b).

➙ (53 + 43)(53 - 43).

➙ 96 × 10.

➙ 960.

Therefore, 53² - 43² = 960.

Some More Identities :-

• a² - b² = (a + b)(a - b).

• (a + b)² = a² + b² + 2ab.

• (a - b)² = a² + b² - 2ab.

• (x + a)(x + b) = x² + (a + b) x + ab.
