Taking the square root of both sides of the equation, we have:
√((x+3)^2) = √36
Simplifying the left side of the equation, we have:
x + 3 = ±√36
Since we only need one answer, we can take the positive square root:
x + 3 = √36
Simplifying further, we have:
x + 3 = 6
Subtracting 3 from both sides of the equation, we have:
x = 6 - 3
x = 3
Therefore, the solution to the quadratic equation (x+3)^2 = 36 is x = 3.
Solve the following quadratic equation using square roots: (x+3)^2=36 .
