factor first
what Mrs. Gruman screams at us in Algebra 2H if we don't factor first, and we know it means trouble.
"Factor first or I'll make you eat your homework!", Mrs. Gruman, during the worst day ever.
"Factor first or I'll call your mom!", me, trying to scare my class.
"Factor first or I'll fail you!", Mrs. Gruman, when I messed up the whole chapter.
