In order to illustrate LU-factorization with partial pivoting, we apply the method to the matrix A = 2 1 1 0 4 3 3 1 8 7 9 5 6 7 9 8 , which we factored in Chapter 3 without partial pivoting pivoting. We denote the 4×4 permutation matrix, which keeps track of the row interchanges by P; it is initialized as the identity matrix and so is the lower.

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.

However, instead of first adding the values within the brackets and then multiplying the answer by 3 we may just do the calculation as shown in the table. Which expressions amongst those given in the table are equivalent?
• The sum and product of the roots can be rewritten using the two formulas above. Example 1 The example below illustrates how this formula applies to the quadratic equation x 2 + 5 x + 6. As you can see the sum of the roots is indeed − b a and the product of the roots is c a . Example 2
