WebExplanation. a x 2 + b x + c = 0. This is the initial equation. a x 2 + b x = – c. Subtract the variable c from both sides to get rid of the + c on the left. x 2 + b a x = – c a. Divide both sides by a to free x 2 of its coefficient. x 2 + 2 b 2 a x = − c a. Rewrite b a as 2 b 2 a x so that the second term is 2 p q. WebWith the quadratic equation in this form: Step 1: Find two numbers that multiply to give ac (in other words a times c), and add to give b. Example: 2x2 + 7x + 3. ac is 2×3 = 6 and b is 7. So we want two numbers that multiply together to make 6, and add up to 7. In fact 6 and 1 do that (6×1=6, and 6+1=7)
