-2x>6

3. Yahoo!

-2x > 6 nw multiply with -1 so inequatitly reversed 2x < -6 x < -3 Soln = (-infinit , -3)

4. lexigolds9

are they in ()'s or []'s

5. lexigolds9

or different on each side?

$\{x\ |\ x<-3, x \in \mathbb{R} \}$

11. lexigolds9

i got -infinity,-3 ,,, i just need to know when graphing would it be ] or )

12. lexigolds9

at the negitave 3

its paranthesis at -3

14. lexigolds9

thank you so much

np :)

16. lexigolds9

can u by any chance tell me the real solutions for 20x^2+17x-10=0

ok do u know the quadratic formula?

18. lexigolds9

not anymore. lol i can plug in though if you canwrite it out

19. lexigolds9

or u can just give me the answer:) lol

haha smart. well its better to know the formula for your future reference. :) |dw:1350961093023:dw|

21. lexigolds9

17+- square of 17^2-4(20)(-10) over 40 ??

22. lexigolds9

this is really hRD

haha hold im trying to figure out if we can factor out the equation

so im thinking this mite be the factored form of the equation. (5x+5)(4x-2)=0

and then make it equation to zero and solve
