Does y equals 3x2-5x plus 1 cross the x-axis? - Answers

This can be easily answered using the well-known formulae for solving quadratic equations:y = 3x2 - 5x + 1thenx = (5 +- sqrt(25 - 4*3*1))/6since 25-4*3*1 = 25-12 = 13, which is > 0, this parabola has two intersections with the x-axis (as the quadratic equation has two real roots).
