To solve this, we mutiply the powers by their respective co-efficients, then we lower the power by 1. If there isn't any X value following the number, we ignore the number entirely because it is a constan...

2x(2x-1)=0 x=0 and x=1/2

The geometric series takes the form of ax^n where n is a number from 0 to infinity with 0 being the first number in the series. 

The sum of this series is S = a + ax + ax^2 + ... 

If we brea...

180-99-22= 68

180-68= 112

112/2=56

With integration like this, you can look at each appearance of x individually.  Firstly there is a rule to follow that is the power of X in each case increases by 1 and then that increase power divides th...
