Question 1164839: a developer wants to purchase a plot of land to build a house the area of the plot can be described by the following expression: (5x+1)(6x-7) when x is measured in meters. multiply the binomials to find the area of the plot in standard form Answer by solver91311(24713) (Show Source):
Use the FOIL process: First, Outside, Inside, Last
Multiply the First terms. Then multiply the Outside terms, that is the first term in the first binomial and the second term in the second binomial. Then multiply the Inside terms, that is the second term in the first binomial times the first term in the second binomial. Then multiply the last terms. Then collect like terms as appropriate. Why do it in that order? Because LFOI doesn't spell anything, even though it would work just as well.
