What is the area of the patio in square feet? Write a mathematical expression for the statement that the area is less than or equal to 150 square feet and rewrite this expression in the form $a x^2 + b x + c \leq 0.$ To solve this inequality for $x$ I would first solve $a x^2 + b x + c = 0$ for $x.$ Use these roots to sketch the graph of $y = a x^2 + b x + c .$ For what values of $x$ does the graph lie below the Xaxis?
