Optima Learn · Accepted Answer

First factorize the polynomial P x 2x 3 - 11x 2 17x - 6 x - 3 x - 2 2x - 1 . So the roots are x 3, 2, 2 . These are the radii of the three circles. Areas of circles are proportional to the squares of their radii 3 2 2 2 left 2 right 2 9 4 4 . Multiply all by 4 to clear fractions 36 16 1. Hence, the
