The steps to derive the quadratic formula are shown below:

Step 1: ax2 + bx + c = 0
Step 2: x2 + b over ax + c over a = 0
Step 3: x2 + b over a x = - c over a
Step 4: x2 +b over a x + square of quantity of b over 2 times a = -c over a + square of quantity of b over 2 times a
Step 5: x plus b over 2 times a, all squared = -c over a + square of quantity of b over 2 times a
Step 6: x + b over 2 times a = square root of all of negative c over a plus the square of the quantity b over 2 times a
Step 7: x = - b over 2 times a ± square root of all of negative c over a plus the squ
