x+=+%28-b+%2B-+sqrt%28+b%5E2-4ac+%29%29%2F%282a%29 Start with the quadratic formula


x+=+%28-%28-3%29+%2B-+sqrt%28+%28-3%29%5E2-4%282%29%281%29+%29%29%2F%282%282%29%29 Plug in a=2, b=-3, and c=1


x+=+%283+%2B-+sqrt%28+%28-3%29%5E2-4%282%29%281%29+%29%29%2F%282%282%29%29 Negate -3 to get 3.


x+=+%283+%2B-+sqrt%28+9-4%282%29%281%29+%29%29%2F%282%282%29%29 Square -3 to get 9.


x+=+%283+%2B-+sqrt%28+9-8+%29%29%2F%282%282%29%29 Multiply 4%282%29%281%29 to get 8


x+=+%283+%2B-+sqrt%28+1+%29%29%2F%282%282%29%29 Subtract 8 from 9 to get 1


x+=+%283+%2B-+sqrt%28+1+%29%29%2F%284%29 Multiply 2 and 2 to get 4.


x+=+%283+%2B-+1%29%2F%284%29 Take the square root of 1 to get 1.


x+=+%283+%2B+1%29%2F%284%29 or x+=+%283+-+1%29%2F%284%29 Break up the expression.


x+=+%284%29%2F%284%29 or x+=++%282%29%2F%284%29 Combine like terms.


x+=+1 or x+=+1%2F2 Simplify.


So our answers are x+=+1 or x+=+1%2F2
