Question

Which product is equivalent to 25x2 – 16?

(5x − 4)(5x + 4)
(5x + 8)(5x − 8)
(5x − 4)(5x − 4)
(5x − 8)(5x − 8)

Answer 1

Answer:

(5x − 4)(5x + 4)

Step-by-step explanation:

To find:

Product equivalent to 25x² - 16

Solution:

As we know , a²-b² = (a + b)(a - b)

Similarly,

25x² - 16

(5x)² - (4)²

(5x + 4)(5x - 4)

Hence, the required equivalent product is

(5x + 4)(5x - 4).
