Expand the following:
a. x(x+5)
b. x(3x-1)
c.2x(2x+3)
d.5x(x-3y)

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).

if graphs are part of the problem statement, share them.   .
