x2 – 1.1x + 0.28
13. Factor completely. If the polynomial is prime, state this.
2×2 – 8x + xy – 4y
14. Solve by factoring and using the principle of zero products.
a2 – 19a + 84 = 0
15. Solve the problem.
Two cars leave an intersection. One car travels north; the other east. When the car traveling north had gone 12 miles, the distance between the cars was 4 miles more than the distance traveled by the car heading east. How far had the eastbound car traveled?
