WebSteps for Finding Roots Step 1: Calculate Discriminant Given the equation Ax2+ Bx + C = 0, calculate discriminant D = B2− 4AC Step 2: Find Roots If D = 0, the √Dpart of the formula vanishes. So there is only one (repeated) root: x1= x1= ( − B)/(2A) For other cases, the roots are: x1= ( − B + √D)/(2A) x2= ( − B − √D)/(2A) Let us see an example. ch abbe
