factored form, equations solving for y=ax^2+bx+c, and FOIL programs or ways



Are there any programs or ways to solve for y=ax^2+bx+c in an equation like
2x^2=4y-7, on a TI-86,  so i dont have to solve it on paper? Also, are there
any programs or ways to factor x^2+2x+4 into factored form, (x+n)(x+n), or
some kind of shortcut way to solve it at least? Last, does anybody have a
program or way to do FOIL? All on a TI-86? I know it's a lot, but I truly
appreciate it. Thank you!
