Whats up guys..this is kind of urgent..just these 3 questions I need..

1. Factor the trinomial:
24h^2-22h-35

2. Solve:
5s^2=36s+32

3. Solve the equation:
49s^2+56s=-16

Thanks alot guys..I really appreciate the help (Happy)

Hello, Mike!

You need to brush up on your Factoring . . .

Quote:

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

Quote:

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 . . .

Quote:

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
