please do the two condition for b and detrminant

Question (1): The roots of quadratic equation: ar + bx+c=0 can be determined with the quadratic formula. -b + V162 - 4ac .... (1) X2 2a Develop an algorithm that does the following: Using Excel VBA software X1 Step 1: Prompts the user for the coefficients, a, b, and c Step 2: Implements the quadratic formula, guarding against all eventualities (for example, avoiding division by zero and allowing for complex rools) Step 3: Displays the solution, that is, the values for Step 4: Allows the user the option to return to step 1 and repeat the process, If a = 0. an immediate problem arises because of division by zero. In fact, close inspection of Equation 1 indicates that two different cases can arise. That is, If b +0. the equation reduces to a linear equation with one real root, --c/b. If b = 0, then no solution exists. That is the problem is trivial. If a two possible cases occur depending on the value of the discriminant, d=b2 4ac. That is, Itd 20. two real roots occur If d
