paying algebra help equations!!

[kamaka]

I'm pretty much dumb when it comes to math....anyways i need help with these...I can pay whoever can help me finish these by paypal I have a canadian account I can offer $4-5

Find the discriminant

3x^2+6x-8=0
I already know the a,b,c

a=3,b=6,c=-8

5x^2+3x=12 (have to put in standard form first
7-5x^2+9x=x (have to put in standard form first i think
2x=x^2-x (have to put in standard form first

Determine the number of solutions in the equation one, two, or none

x^2-3x+2=0
-3x^2+5x-1=0
x^2-2x+4=0
3x^2-6x+3=0
-5x^2+6x-6=0

Thanks please private message me or you can put them as a response and i can pay you then thanks

Allright.

1)3x^2+6x-8=0
Discriminant = 4

2) 5x^2+3x=12
In standard: 5x^2+3x-12=0.
Discriminant = Root from 69.

3)7-5x^2+9x=x
In standard: -5x^2+8x+7=0
Discriminant = Root from 204.

4)2x=x^2-x
In standard: x^2+x=0
Discriminant = 1

5)x^2-3x+2=0
Number of solutions = 2

6)-3x^2+5x-1=0
Number of solutions = 2

7)x^2-2x+4=0
Number of solutions = 1

8)3x^2-6x+3=0
Number of solutions = 1

9)-5x^2+6x-6=0
Number of solutions = 0

I PM-ed you my PayPal.
