Question

Josephine solved a quadratic equation: (x+6)^2=49. Her work is shown below.
Step 1: √(x+6)^2 = √49
Step 2: x+6 = 7
Step 3: x = 7−6
Step 4: x = 1
In which step did Josephine make an error?
A- step 4
B- step 1
C- step 2
D- step 3
Step 1: √(x+6)^2 = √49
no
Step 1: √(x+6)^2 = +or-√49
so
x + 6 = 7
or
x + 6 = -7
x = 1
or x = - 13
