Question

The factors of a² - 625 = ?​

Answer 1

Step-by-step explanation:

(a^2)-(5^2)^2

(a^2+5^2) (a^2-5^2)

(a^2+5^2) (a+5)(a-5)

Answer 2

Step-by-step explanation:

factors of given equation :

$a {}^{2} - 625 = a {}^{2} - (25) {}^{2} \\ = (a - 25) \times (a + 25) \\ = (a - 25)(a + 25)$

using formula

$a {}^{2} - b {}^{2} = (a + b)(a - b)$
