This online calculator will solve the polynomial with an order of 2 such as ax^{2} + bx + c = 0 for x although, answers will not always be fully reduced or simplified. See notes below.

This will solve quadratic equations (polynomials with an order of 2) using the quadratic formula:

x = [ -b ± sqrt(b^{2} - 4ac) ] / 2a
