+4%2F%28m%5E2-7%29+=+1+
+4+=+m%5E2-7+
+11+=+m%5E2+
+m+=+sqrt%2811%29+ or +m+=+-+sqrt%2811%29+

+m+=+16t%5E2%2Bvt%2B7+
+%28m-7%29%2F16+=+t%5E2%2B%28v%2F16%29t+

let 2a = v/16
so a = v/32

therefore having +%28m-7%29%2F16+=+t%5E2%2B%28v%2F16%29t+%2B+%28v%2F32%29%5E2+-+%28v%2F32%29%5E2+ is still the same thing as before, however we can now write it as:

+%28m-7%29%2F16+=+%28t%2B%28v%2F32%29%29%5E2+-+%28v%2F32%29%5E2+
+%28m-7%29%2F16+%2B+%28v%2F32%29%5E2+=+%28t%2B%28v%2F32%29%29%5E2+
+%28m-7%29%2F16+%2B+%28v%5E2%2F1024%29+=+%28t%2B%28v%2F32%29%29%5E2+
+%2864%28m-7%29%29%2F1024+%2B+%28v%5E2%2F1024%29+=+%28t%2B%28v%2F32%29%29%5E2+
+%2864m-448%29%2F1024+%2B+%28v%5E2%2F1024%29+=+%28t%2B%28v%2F32%29%29%5E2+
+%2864m-448%2Bv%5E2%29%2F1024+=+%28t%2B%28v%2F32%29%29%5E2+
+- +sqrt%28%2864m-448%2Bv%5E2%29%2F1024%29+=+t%2B%28v%2F32%29+
+%28-v%2F32%29+%2B-+sqrt%28%2864m-448%2Bv%5E2%29%2F1024%29+=+t+
+%28-v%2F32%29+%2B-+%28sqrt%2864m-448%2Bv%5E2%29%29%2F32+=+t+
+%28-v+%2B-+sqrt%2864m-448%2Bv%5E2%29%29%2F32+=+t+
