Hi everyone. Would someone be able to help me with this problems? I know it's a lot, if you only want to help with one or two, that is fine!!
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.

Tell me what you are stuck on each one, and maybe I can help. I am not inclined to do them for you.
