A school plans to expand its rectangular vegetable garden. Both the length and the width will be increased by x feet. After the expansion, the garden will have an area of (x^2 + 12x + 32)
square feet. What are the original length and width of the garden? Explain how you used
factoring to determine your answer.

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).

answer: a parabola

steps:

(x-1)(x+4)   = x(x+4) - 1(x+4) = (x^2 + 4x) - (x+4)

                = x^2 +4x -x -4   = x^2 +3x -4

which is a parabola
