Solve for x in the equation 2 x squared minus 5 x + 1 = 3. x = five-halves plus-or-minus StartFraction StartRoot 29 EndRoot Over 2 EndFraction
x = five-halves plus-or-minus StartFraction StartRoot 41 EndRoot Over 4 EndFraction
x = five-fourths plus-or-minus StartFraction StartRoot 29 EndRoot Over 2 EndFraction
x = five-fourths plus-or-minus StartFraction StartRoot 41 EndRoot Over 4 EndFraction

Can someone me out here and the tell me the greatest common factor
