How are you getting that (2)(k<sup>2</sup>) equals 2, or that (-5/k)(k<sup>2</sup> is still -5/k...? Did you forget that "multiplying through on both sides" means "multiplying through onto every term on each side"?spear33 said:If you multiply both sides by k^2 is it supposed to look like this: 2 - 5/k + 2 = 0 * k^2
That should be +5 : -(-5) = 5; so:spear33 said:k= -5 plus or minus the square root of 41 divided by 4
Sorry I dont know how to make it into an image file or anything like that.
[Edit] Just caught my mistake its 9 not 41
No prob; no worries. But if you would like to learn how to format with LaTeX (and if I can do it, it can't be that hard!), then follow the lower links in the "Forum Help" pull-down menu at the very top of the page.spear33 said:I dont know how to make it into an image file or anything like that.
