Geometry The figures below are squares. Find an expression for the area of each shaded region. Write your answers in standard form.

Answer:
shaded area = 2x² + 6x + 17
If these are squares, what is the "x + 3"?
Step-by-step explanation:
shaded area = (x + 4)² - (x - 1)² = x² + 8x + 16 + x² - 2x + 1 = 2x² + 6x + 17
