Verica didn't solve this radical equation correctly. Here is their work:

Your turn; x+3 = V1 + 2x

X

2x-2 = x-1

(zoa) = (-1)

2x-2=X²+1

0 =X²-2x-3

O=(x-3)(x+1)

x=3 or x=1

.

Why does Verica (correctly) square both sides of the

equation in Step 2?

.

What mistake does Verica make between Step 2 and

Step 3? Fix Verica's work below.
