Explanation:
#"using the a-c method to factor the quadratic"#
#"the factors of the product "3xx6=18#
#"which sum to " - 11" are " - 9 " and " - 2#
#"split the middle term using these factors"#
#3x^2-9x-2x+6larrcolor(blue)"factor by grouping"#
#=color(red)(3x)(x-3)color(red)(-2)(x-3)#
#"take out the "color(blue)"common factor "(x-3)#
#=(x-3)(color(red)(3x-2))#
#3x^2-11x+6=(x-3)(3x-2)#
