Can someone help me solve #1 and #9 in the picture, I'm having trouble on getting started with these problems and understanding the quadratic formula.
*UPDATE: I attached the file of the image scan to this thread can you see it now?*
Use a similar procedure to find :
For 9 and 10, know that the median of a right triangle (on its hypotenuse) divides the triangle into two smaller isosceles triangles (the length of this median is half the length of the hypotenuse).
