Megan factored the expression 72x^243x+6 as (9x3)(8x2). But when Jacob applied the FOIL principle and multiplied out (9x3)(8x2), he got72x^242x+6; thus, Megan’s solution does not appear to check. Why is that? Please help Megan to understand this better. Explain your reasoning and correctly factor the original expression, if possible. If the expression is prime, so state
