Use a geometric model to factor x2 + 3x + 2 by following these
steps:
step 1: model the trinomial by placing tiles in the product
section to form a rectangle at the top left. the x- tile
is already in the correct place.

The customer price index(cpi), which measures the cost of a typical package of customer goods, was 208.8 in 2011 and 244.1 in 2016.let x=11 corresponding to the year 2011 an estimate to cpi into 2013 and 2014. assume that the data can be modeled by a straight line and the trend to continue idenfinitely. use data points to find such a line and then estimate the requested quantities
