You didn't indicate your directions for these. I'll assume you're trying to SOLVE each equation for the variable involved.
A good suggestion is to see if you can divide each term by a common factor.
In your first equation, you can divide each term by 2. When you do that, you get
x[sup:wf4a3hae]2[/sup:wf4a3hae] + 4x + 4 = 0
Now, that should be fairly easy to factor, or you can use the quadratic formula.
For the second equation, you can divide each term by 3:
16q[sup:wf4a3hae]2[/sup:wf4a3hae] + 56q + 49 = 0
Again, that should be fairly easy to factor...hint: it's the square of a binomial.
If you're still having trouble, please repost, showing all of the work you've done to attempt a solution. We can help best if we see your work so we can tell where your difficulties lie.
