for all of the problems, all you have to do is bring everything to one side

then you'll have ax^2-bx+c

then you can use the quadratic equation:

x= (-b +/- ((-b)^2 -4ac)^1/2))/2a

here is a nicer version of the formula:

and then you just sub in the number and you'll get an answer

(sorry i'm new, and maybe not the best person at explaining)

EDIT: this works for numbers 2 and 3, although i think that Soroban's method is a lot easier :P
