Make a flowchart to solve ax2 + bx + c = 0 for roots real. Identify the data and results. You can use the operations you need. Make sure the result is valid.

Problem analysis: If a 0 there are three cases:

First, with two solutions given with the formula corresponding to the equation of second degree when the discriminant is positive.

Second, with a solution given by the formula when the discriminant is zero.

Third, with two complex solutions, given by the formula when the discriminant it is negative.

If a = 0, three cases arise:

First, it is when b  0 whose solution is= -c/b  Second, it is when b = 0 and c = 0, that an identity is evident.  Third, when b = 0 and c  0 that has no solution.
