## anonymous one year ago 2) 2/5x^2 -x+ 19/15 =0

1. anonymous

lol

2. just_one_last_goodbye

anyways lets see how i can help

3. just_one_last_goodbye

is the first 2 part of the equation or no?

4. anonymous

$\frac{ 2 }{ 5 }x^2-x+\frac{ 19 }{ 15 }=0$

5. anonymous

I hope that makes it better

6. just_one_last_goodbye

Much better ^-^

7. anonymous

So I know A= 2/5 B= -1 C= 19/15

8. just_one_last_goodbye

9. anonymous

yes

10. just_one_last_goodbye

and Solving for x?

11. just_one_last_goodbye

x = 1.455485

12. anonymous

it says "Use the quadratic formula to solve the equation." "A. The solution set is ____" (simplify your answer. type an exact answer, ysing radicals as needed. Use intefers or fractions for any numbers in the expression. Use a comma to separate answers as needed.) "B. the solution is (emptyset)"

14. anonymous

lol my b

15. just_one_last_goodbye

~passes skittles~

16. anonymous

omg. skittles with coffee

17. anonymous

yes

18. just_one_last_goodbye

^

19. just_one_last_goodbye

Oh quadratic thought it was a normal equation sorry

20. anonymous

lol, the only unit i have left is quadratic and I haven't done it in 2 years

21. just_one_last_goodbye

hmm idk it's not giving me an answer

22. anonymous

okay it's okay, let's move on to the next question?

23. just_one_last_goodbye

sure

24. anonymous

.6x^2 = 1.2x+0.6

25. anonymous

$0.6x^2-1.2x-0.6=0$

26. just_one_last_goodbye

wait is it an addition problem or subtraction?

27. anonymous

I just flipped it so it's in standard form. it's still quadratic. just now it's all on one side.

Open this attachment up, It should help ^-^

what site did you use?

HI!!

$\frac{ 2 }{ 5 }x^2-x+\frac{ 19 }{ 15 }=0$ is annoying multiply by 15 and get $6x^2-15x+19=0$ then it will be much easier

34. misty1212

you can use the quadratic formula or if you are a factoring wiz you can try that

35. anonymous

yeah. I'm on here, asking for help. I'm not a factoring wiz.

36. misty1212

ok well is it really $\frac{ 2 }{ 5 }x^2-x+\frac{ 19 }{ 15 }=0$?

37. misty1212

because that equation has no real solutions, maybe there is a typo there

38. anonymous

yes. that's how it's written on my problem

39. anonymous

well one of the answers is there is no solution

40. misty1212

then either you are supposed to come up with two ugly complex solutions, or say "no solution"

41. anonymous

so you sorta answered my question

42. misty1212

ok fine in any case you really want to multiply by 15 first and start with $6x^2-15x+19=0$ then, when you use the quadratic formula, you will see that there is no answer

43. misty1212

you do not want to use decimals you do not want to use fractions you want to work with integers only

44. anonymous

okay, thank you
