Consider:
x²+4x-60=0
"What do I do now?" Asks the student. And we tell them to write some parentheses like this:
(x ?)(x ?)=0
Hopefully the concept of multiplying binomials is a familiar one before you get to this. And the idea of the "zero product property" (I think the zero product property is so cool but have not found a way to get students as excited about it as I am... it's a pretty neat algebra trick... anyway)
When students see:
(x ?)(x ?)=0
They groan. 2/
