Consider the steps for solving 3x^2 - 42x + 9 = -5 for x by completing the square.

step 1) 3x^2 - 42x = -14
step 2) 3(x^2 - 14x) = -14
step 3) 3(x^2 - 14x + 49) = -14 +

what number should be added to the right side of the equation?

me !

We should add 147 to the right side of the equation.

Step-by-step explanation:

Since, When we solve a quadratic equation by completing the square.

We follow the following steps,

Step 1 : Move the constant term to the right side of the equation

Step 2 : Make 1 as the coefficient of

Step 3 : Complete the square on the left side of the equation and add the same value to the right side of the equation.

Thus, by the above explanation the steps for solving are as follow,

Step 1 :

Step 2 :

Step 3 :      

two data sets with the same median will not have the same varaibility
