Answer:

c = -5

Step-by-step explanation:

Plug in -5 to c in the equation:

c² - 25 = 0

(-5)² - 25 = 0

Simplify. First, solve the power, then solve the subtraction:

(-5)² - 25 = 0

(-5 * -5) - 25 = 0

(25) - 25 = 0

0 = 0 (True)

Answer:

c=-5

Step-by-step explanation:

c^2-25=0

I'm going to solve this by using square root after I get the square termed by itself.

[tex]c^2-25=0[/tex]

Add 25 on both sides:

[tex]c^2=25[/tex]

Square root both sides:

[tex]c=\pm \sqrt{25}[/tex]

[tex]c=\pm 5[/tex]

Check!

[tex](5)^2-25=0 \text{ and } (-5)^2-25=0[/tex]
