IF YOU HAVE ANY MERCY, PLEASE HELP ME FIGURE THESE MATH PROBLEMS OUT! (only, if you know how to do them :0 )
7. Solve the quadratic equation 2x2-13x-7=0 by factoring.
8. What is the value of the discriminant for the equation in question 7? What do you know about the roots from that value
10. Graph the quadratic equation (y = 2x 2-13x-7) using the MathResources graphing tool; and attach it with this assignment in the Assignment Area. Note: You may need to change the values of x-from & to and y-from & to so that the entire parabola will be visible on the grid. Also save as instructed in note 5 under graphing. Otherwise I will have to send it back. To use the graphing tool click on the button below.
11. What are the values of the roots you found using track points? Round to the nearest hundredths.
