Question 150372
1. Graph the following quadratic functions
a. F(x)= -x^2-2x+2
b. F(x)= -x^2+3x+2
c. F(x)= x^2+2x+2
d. F(x)= x^2-2x-2 

2. Solve the equation and check the proposed solutions 2/x+2/x+1 = 3x-1/x^2-1. Show all work
-------------------
1a {{{F(x) = -x^2-2x+2}}}
*[invoke solve_quadratic_equation -1,-2,2]
Further simplified:
x1 = -1+sqrt(3)
x2 = -1-sqrt(3)
++++++++++++++++++
The other 3 are done the same way.

2. This is ambiguous and needs clarification.
The right side could mean 3x - (1/x^2) - 1, or 3x - 1/(x^2-1). Add parentheses, they're free.
