Number 1 is not factorable but number 2 and number 3 are factorable. Number 1 is solvable using the general solution obtained through Completing the Square and the solutions for it are:

x=%28-8%2B-+sqrt%288%5E2-4%2A1%2A%28-6%29%29%29%2F2
x=%28-8%2B-+sqrt%2864%2B24%29%29%2F2
x=%28-8%2B-+sqrt%2888%29%29%2F2
x=%28-8%2B-+2sqrt%2822%29%29%2F2
highlight%28x=-4%2B-+sqrt%2822%29%29
