Problema Solution

Solve the equation (x+3)^2=64 by the square root property.

Answer provided by our tutors

(x+3)^2=64

(x+3)^2=8^2

x + 3 = 8 or x + 3 = -8

By solving x + 3 = 8 we have x = 8 - 3 = 5.

By solving x + 3 = -8 we have x = -8 - 3 = -11.

So the solutions for (x+3)^2=64 are 5 and -11.
