Verify results using the two formulas for **Sum** & **Product** **of** **Roots**. IV) Finding the **Sum** **and** **Product** **of** **the** **Roots** using the formulas: (Student and Teacher guided) a) Let's look at the standard form of the Quadratic equation. **1** Answer. bp. Apr 9, 2015. **Sum of** the **roots** = − 2 3 **and product 0**. Make the coefficient of x2 as **1** by dividing the equation by 3. x2 + 2 **3 x** +**0**=**0**. The negative of the. The **sum of** the **roots** is (5 + √2) + (5 − √2) = 10. The **product of** the **roots** is (5 + √2) (5 − √2) = 25 − 2 = 23. And we want an equation like: ax2 + bx + c = **0**. When a=**1** we can work out that:.

We can "complete the square" in the parentheses by adding 2*1/16. To keep the equation balanced we also need to substract 2*1/16 = 1/8: y = 2 (x^2 -1/2x + 1/16) - 1/8 - 15 y = 2* (x - 1/4)^2 - 1/8 - 15 y = 2* (x - 1/4)^2 - 121/8 In this case then a = 2 and the vertex (h,k) = (1/4,-121/8). Solve the cubic equation x 3 - **6** **x** 2 + 11x - 6 = 0. Solution To solve this problem using division method, take any factor of the constant 6; let x = 2 Divide the polynomial by x-2 to (x 2 - 4x + 3) = 0. Now solve the quadratic equation (x 2 - 4x + 3) = 0 to get x= **1** or x = 3 Therefore, the solutions are x = 2, x= **1** **and** x =3. Example 6.
