Question

What type of factoring is this? x^2-25
Step by step :)

Answer 1

Take the square root of 25 to factor this equation out.

The equation will look like this:

`x^(2) -5^(2)` (this is the
`a^(2) -b^(2)` = (a-b)(a+b) property)

= (x-5)(x+5)

Answer 2

To Find :

• we need to factorize x² - 25

Solution :

x² - 25 can be written as x² - (5)²

›› x² - (5)²

By using identity a² - b² = (a + b)(a - b)

›› (x + 5)(x - 5)
