It is also shown that from the four equations of this system it is enough to solve two equations, the solution of the other two can be obtained from these. Using some earlier results, we also determine the general measurable solutions of the functional equation f(xy) − f(x(1 − y...
When x<15 we are going to have 4x−60<0, therefore |4x—60| can be expressed in the form 60−4x. We have the equation x=60−4x⇒5x=60⇒x=12. Since 12 is less than 15, 12 is another possible solution. X=|2x—|60−2x||. ...

So "the product of $$x$$ minus a root multiplied by $$x$$ minus the other root is equal to the quadratic equation that has these roots as a solution". Example If the solutions of the equation are $$x_1=4,x_2=2$$ the corresponding quadratic equation is: $$$(x-4)(x-2)...
This equation shows the partitioning of the total variation in Y, the dependent variable, about its mean into an among (or between)-group component and a within-group component. These sum of squares are called the total sum of squares corrected for the mean (SST), the among (or between)...
