You can put this solution on YOUR website!
sqrt%282x+-+1%29+%2B+x+=+4
sqrt%282x+-+1%29+=+-x+%2B+4
sqrt%282x+-+1%29%5E2+=+%28-x+%2B+4%29%5E2
2x+-+1+=+x%5E2+-+8x+%2B+16
0+=+x%5E2+-+10x+%2B+17
a=1 b=-10 c=17
x+=+%28-b+%2B-+sqrt%28+b%5E2+-+4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
x+=+%2810+%2B-+sqrt%28+100+-+68+%29%29%2F%282%29+
x+=+%2810+%2B-+sqrt%28+32+%29%29%2F%282%29+
x+=+%2810+%2B-+4%2Asqrt%28+2+%29%29%2F%282%29+
x+=+5+%2B-+2%2Asqrt%28+2+%29+
Plug Them In (only one works) :
x+=+5+-+2%2Asqrt%28+2+%29
