Answer:

(x+5)(x-5)

Step-by-step explanation:

x^2 - 25

This can be written as

x^2 - 5^2

We know that this is the difference of squares

a^2 - b^2 = ( a+b) ( a-b)

x^2 - 5^2 = (x+5)(x-5)

Answer:

B. (x + 5)(x - 5)

Step-by-step explanation:

Factor the following:

\longrightarrow x² - 25

25 = 5²:

\longrightarrow x² - 5²

Factor the difference of two squares.

a² - b² = (a + b)(a - b):

\longrightarrow (x + 5)(x - 5)

Write the equation in standard form for the circle with center (5,0) passing through (-1, 9/2)
andreev551 [17]

Answer:

(x - 5)^2 + y^2 = 225/4,

or you could write it as (x - 5)^2 + y^2 = 56.25.

Step-by-step explanation:

The factor form is

(x - h)^2 + (y - k)^2 = r^2  where the center is (h, k) and r = the radius.

So we have:

(x - 5)^2 + (y - 0)^2 = r^2

As the point  (-1, 9/2) is on the line:

(-1 - 5)^2 +  (9/2)^2 = r^2

r^2 =  36 +  81/4

r^2 = 225/4.

So  substituting for r^2:

(x - 5)^2 + (y - 0)^2 = 225/4

(x - 5)^2 + y^2 = 225/4 is the standard form.
