Hey, I have a couple of Lesson Plans for this topic under Square Roots--look for Basic Algebra Square Roots!!

%288%2B3%2Asqrt%28x%29%29%285-4%2Asqrt%28x%29%29

This is a FOIL problem with square roots!!

40+-+32%2A+sqrt%28x%29+%2B+15%2A+sqrt%28x%29+-+12%2Asqrt%28x%5E2%29
40+-+17%2A+sqrt%28x%29+-+12x+
