    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

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

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

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

    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.

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