The table shows the steps and
explanations that can be used
to solve
Vx- 5x=-4.
Which step in the table
I could have created an
extraneous solution?
Work

Step 1 VX-5x-4
x=25x²-40x+16
Step 2
Step 3 0-25x²-41x+16
Step 40-(25x-16)(x-1)
Step 5 (25x-16)-0 or (x-1)-0
Step 6 25x16 or x = 1
Step 7x- or x=1
Explain your reasoning here.
