Question

0=(x+2) squared minus 25

Answer 1

x = - 7, x = 3

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

Answer 2

x=3

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
