Solve the following:
1.) x2 + 2x + 9 = 0
2.) x2 - 7x = -13
3.) -3x2 - 4x - 4 = 0
4.) 3x2 = -12x - 15
5.) -2x2 - 16x - 44 = 0

we are to solve each trinomial. this should cost more points than any other items to be solved.
The discriminants of all equations are negative hence the roots are imaginary numbers
1. x = -1 +- 2.8284 i 2. x = 3.5 +- 0.8660 i 3. x = -2/3 +- 0.9428 i 4. x = -2 +- i 5. x = -4 +- 2.4495 i 

the anwser is b
