Question

X = –5 x = –25 x = 5 or –5 no solution

Answer 1

Answer:

x = 5 or –5

Step-by-step explanation:

x^2        25

------- = ------

x+5       x+5

Using cross products

x^2 (x+5) = 25 (x+5)

Divide each side by (x+5)

x^2 (x+5)/(x+5) = 25 (x+5)/(x+5)

x^2 = 25

Take the square root of each side

sqrt(x^2) = ±sqrt(25)

x = ±5
