(x^{2} - 5) - (x^{2} - 25)

20

Solution steps

(x^{2} - 5) - (x^{2} - 25)

Apply rule:

(a) = a

(x^{2} - 5) = x^{2} - 5

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

Apply the distributive law:

- (a - b) = - a + b

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

= x^{2} - 5 - x^{2} + 25

Group like terms

= x^{2} - x^{2} - 5 + 25

Add similar elements:

x^{2} - x^{2} = 0

= - 5 + 25

Add the numbers:

- 5 + 25 = 20

= 20
