## bmxrider Group Title Only one question I cannot figue out. can someone help please. What are the solutions? 1/2x^2+ 2x + 3 =0 one year ago one year ago

1. freakeo98 Group Title

2. freakeo98 Group Title

subtract 3 from both sides

3. bmxrider Group Title

what like terms, sorry I am having a lot of problems with this.

4. freakeo98 Group Title

lol dude its ok, equations can be confusing to some

5. freakeo98 Group Title

$\frac{ 1 }{ 2 }x^2+2x+3=0 thats what ur starting out with$

6. freakeo98 Group Title

thats what ur starting with *

7. bmxrider Group Title

right. Than you want to get the three to the other side right.

8. freakeo98 Group Title

u can do that first. the thing with equations is that there is no direct way of solving it. there r many ways. just make sure what ever u are doing, make sure it mathimatically makes sense

9. bmxrider Group Title

1/2^2+2x=-3

10. freakeo98 Group Title

good, now simplify 1/2^x+2x

11. bmxrider Group Title

19. freakeo98 Group Title

20. bmxrider Group Title

yes

21. freakeo98 Group Title

ok. put 1 divided by 2 and square it

22. freakeo98 Group Title

23. freakeo98 Group Title

24. bmxrider Group Title

0.25

25. freakeo98 Group Title

which is 1/4

26. bmxrider Group Title

I really need help on this to finish a test! last question.

27. CliffSedge Group Title

@freak098 , you clearly do not understand the question - none of what you said is valid here.

28. CliffSedge Group Title

This is a quadratic equation, and doesn't look factorable at first glance. Quadratic formula is your best option.

29. bmxrider Group Title

I think you use the quadratic formula. Am I correct?

30. bmxrider Group Title

yes

31. CliffSedge Group Title

Quadratic formula always works, so is typically the weapon of choice in this situation. A good way to start though, is to multiply everything by 2 first to clear the fraction.

32. bmxrider Group Title

2(1/2x^2+2x+3=0(2) x^2+4x+6=0 correct?

33. CliffSedge Group Title

Yeah, then use the QF on that.

34. bmxrider Group Title

ok. I think I got it now. It was the 1/2 I was confused on. Thank you very much.

35. CliffSedge Group Title

No problem. When I tried it, I was getting non-real answers, so don't be surprised about that.

36. bmxrider Group Title

ok. I will try it
