sqrt%28x+-+1%29+=+%28x+-+3%29
x+-+1+=+%28x+-+3%29%5E2
x+-+1+=+x%5E2+-+6x+%2B+9
0+=+x%5E2+-+7x+%2B+10
0+=+%28x+-+2%29%28x+-+5%29
x = 2 and x = 5
Check:
a. sqrt%28x+-+1%29+=+%28x+-+3%29
sqrt%282+-+1%29+=+%282+-+3%29
sqrt%281%29+=+-1
Wrong
b. sqrt%28x+-+1%29+=+%28x+-+3%29
sqrt%285+-+1%29+=+%285+-+3%29
sqrt%284%29+=+2
Correct
~ Answer: x = 5
