Answer 1

$\huge{\tt{\red{❥}\green{A}\purple{N}\pink{S}\blue{W}\orange{E}\red{R}}}$

$\pink\longrightarrow$ (10-2)(10+2)

$\pink\longrightarrow$ ( 8 ) ( 12 )

$\pink\longrightarrow$ 96

Answer 2

Answer:

96

Explanation:

To evaluate (10 + 2) (10 - 2)

Using identity: (a + b) (a - b) = a² - b²

a = 10

b = 2

(a + b) (a - b) = (10 + 2) (10 - 2)

So,

a² - b² = [10² - 2²]

⇒ 100 - 4

⇒ 96

∴ (10 + 2) (10 - 2) = 96
