My book tells the following:
Multiply y-7=0 by y and the result is 2y^2-14y=0
Multiply x-6=0 by x and the result is x^2-6x=0
One result shows a coefficient of 2; the other result does not. The equations are nearly identical in structure, so, in the result of the first one, where does the coefficient "2" come from in 2y^2 ? OR, why isn't there a coefficitent of 2 preceeding x in the result of the second statement?
Thank you.
