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)

Answer:

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

The equation will look like this:

[tex]x^{2} -5^{2}[/tex]         (this is the [tex]a^{2} -b^{2}[/tex] = (a-b)(a+b) property)

= (x-5)(x+5)
