How to solve the quadratic equation on problem below:
The length of a rectangle is 4m more than the width. The area is 30m2.find the width and length.
~~~~~~~~~~~~~~~~~~~~~~~~~~~ 

W*(W+4) = 30,

W%5E2+%2B+4W+-+30 = 0,

W%5B1%2C2%5D = %28-4+%2B-+sqrt+%2816%2B4%2A30%29%29%2F2 =  you do calc. and take the positive root.
