Instructions:
Plug in the coefficients into each box. If the equation has a 'missing term' (for example, no x2 term), then enter it as a zero.
If your equation is Quartic (in the form of ax4 + bx3 + cx2 + dx + e = 0), simply enter in the coefficients like normal. If your equation is Cubic (in the form of: ax3 + bx2 + cx + d = 0), enter in a 0 into the x4 field and then enter the coefficients as normal. If the equation is Quadratic (in the form of ax2 + bx + c = 0), enter in a 0 into both the x4 AND x3 fields and then enter the coefficients as normal.
Note: Update V3.2 and V3.5 has introduced the option to use special functions and constants. Click here for more information.

Quartic: 15x4 - 58x3 + 8x2 - 80x + 64 = 0
Cubic: 3x3 - 10x2 + 14x + 27 = 0
Quadratic: 10x2 - 28x + 16 = 0
