An athletic field is a 42 yd-by-84 yd rectangle, with a semicircle at each of the short sides. A running track
20 yd wide surrounds the field. If the track is divided into eight lanes of equal width, with lane 1 being the
inner-most and lane 8 being the outer-most lane, what is the distance around the track along the inside
edge of each lane?

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629
