You can put this solution on YOUR website!
2X^2-6X+1=3
2X^2-6X+1-3=0
2X^2-6X-2=0
2[X^2-3X-1]=0
X^2-3X-1=0
Compare to standard form,
a=1
b=-3
c=-1


x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+


x+=+%28-%28-3%29+%2B-+sqrt%28+%28-3%29%5E2-4%2A1%2A-1+%29%29%2F%282%2A1%29+


x+=+%283+%2B-+sqrt%28+9%2B4+%29%29%2F%282%29+


x+=+%283+%2B-+sqrt%2813+%29%29%2F%282%29+


Root 13=3.6055=3.606


x=(3+6.606)/2 AND (3-6.606)/2
x=4.803 AND -1.803


Solution Set={4.803,-1.803}


Hope this helps,
best of luck.
