Help Harvey was mulitplying the two binomials together using the FOIL method. Which of the following statements is true about his work? (2x+1)(3x-2) =(2x)(3x)+(2x)(2)+(1)(3x)+(1)(-2) =6x^2+4x+3x-2 =6x^2+7x-2

    Notice how he wrote "(2x)(3x)" that's to reflect the multiplication of the first terms (F in FOIL stands for First) |dw:1433625059881:dw|

    but things fall apart when he gets to (2x)(2) which is the O (outer) part of FOIL |dw:1433625106088:dw| it should be (2x)(-2) instead

    Harvey did not multiply the OUTER terms correctly.
