How do you simplify the product #(6x - 5)(3x + 1)# and write it in standard form?
#"each term in the second bracket is multiplied by each"#
#"term in the first bracket"#
#=18x^2color(blue)(+6x)color(blue)(-15x)-5larrcolor(blue)"collect like terms"#
#=18x^2-9x-5larrcolor(magenta)"in standard form"#
Try using the FOIL method (First, Outside, Inside, Last)
You have to multiply each term in the left bracket by each term in the right bracket. The easiest way to make sure you don't miss anything is to use a systematic method such as FOIL.
The FOIL method means selecting those pairs of numbers to multiply together
Now we add them together
