Answer:
x=3
Step-by-step explanation:
0=(x+2)^2-25
+25 +25
25=(x+2)^2
Square root both sides to get:
5=x+2
-2 -2
3=x
Answer:
x = - 7, x = 3
Step-by-step explanation:
0 = (x + 2)² - 25 ( add 25 to both sides )
25 = (x + 2)² ( take square root of both sides )
± 5 = x + 2 ( subtract 2 from both sides )
- 2 ± 5 = x
then
x = - 2 - 5 = - 7
x = - 2 + 5 = 3
