Question

Factorize xsquare-25​

Answer 1

Answer:

The answer is (x + 5)(x - 5).

Step-by-step explanation:

Assuming that 25 is a perfect square so you can apply :

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

Test :

$(x+5)(x-5) = {x}^{2} - 5x + 5x - 25$

$(x+5)(x-5) = {x}^{2} - 25$

Answer 2

Answer:

$\boxed{(x-5)(x+5)}$

Step-by-step explanation:

x² - 25

Factor out square.

(x)² - (5)²

Apply difference of two squares formula.

a² - b² = (a-b)(a+b)

a = x

b = 5

x² - 25 = (x-5)(x+5)
