9. Could you show how to use factoring and the zeroproudct property to find the zeros of each quadratic function? f(x)=x^29x
11. Same directions as above f(x)=4x^24x+1
14. x^2+8x+4=0 (solve this quadratic equation by completing the square)
15. 2x^211x+5=0 (also solve by completing the square)
16. The area of a triangle is 24 square inches. The height is 4 inches shorter than the base. Find the height and the base of the triangle.
