    Hello, Mike!

    You need to brush up on your Factoring . . .


    1. Factor the trinomial: . 24h^2-22h-35
    (4h-7)(6h+5)


    2. Solve: . 5s^2\:=\:36s+32
    We have: . 5s^2 - 36s - 32 \:=\:0

    Factor: . (5s + 4)(s - 8) \:=\:0


    I assume you can finish this problem now . . .



    3. Solve: . 49s^2+56s\:=\:-16
    We have: . 49s^2 + 56s + 16 \:=\:0

    Factor: . (7s + 4)(7s + 4) \:=\:0 . . . etc.

    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
