Help Math algebra a! paying Runescape pure wc.

[kamaka]

I'm paying a pure woodcutting runescape level 3 with 83 woodcutting and some yew logs/willows.

Anyways I need help doing these with work if anyone can help.

Find the values of b^2-4ac and describe the # of solutions either 1,2, or none

x^2-6x-2=0
2x^2-4x-8=0

rewrite the equation in standard form, use the quadratic formula to solve the equation.

x^2=-11x+-10
x^2-2x=3

solve the equation.

x^2=64
y^2=4
5x^2=-45
x^2-9=27
3y^2-4=23

Thanks.

1. x = 3 +/- sqrt(11) , 2 solutions
2. x = 1 +/- sqrt(5) , 2 solutions

3. x^2 + 11x + 10, x = -10, -1
4. x^2 - 2x - 3, x = -1, 3

5. x = +/- 8
6. y = +/- 2
7. Undefined
8. x = +/- 6
9. y = +/- 3

I don't actually want the pure, so don't worry about it.

1.Not sure
2.not sure

3. x^2 + 11x + 10, x = -10, -1
4. x^2 - 2x - 3, x = -1, 3

5. x = -/+ 8
6. y = -/+ 2
7. undefined I think
8. x = -/+ 6
9. y = -/+ 3

no work?

I don't have a graphing calculator, do you?

Maybe you should quit runescape and learn the maths you are doing in school. Then you'd be able to do your own working out boy!

People generally lie about this kind of thing. Unless you like doing math I wouldn't advocate wasting your time. I will be thoroughly surprised if you get any compensation

True I just wanted to show off my math skills but apparently they aren't very good.
