3v%5E2%2B4v-1=0
Use the quadratic formula.
v+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
v+=+%28-4+%2B-+sqrt%28+4%5E2-4%2A3%2A%28-1%29+%29%29%2F%282%2A3%29+
v+=+%28-4+%2B-+sqrt%28+16%2B12+%29%29%2F%286%29+
v+=+%28-4+%2B-+sqrt%28+28+%29%29%2F%286%29+
v+=+%28-4+%2B-+2sqrt%28+7+%29%29%2F%286%29+
v+=+%28-2+%2B-+sqrt%28+7+%29%29%2F%283%29+
The exact roots are,
v%5B1%5D+=+%28-2+%2B+sqrt%28+7+%29%29%2F%283%29+
v%5B2%5D+=+%28-2+-+sqrt%28+7+%29%29%2F%283%29+
or approximately,
v%5B1%5D+=+0.215+
v%5B2%5D+=+-1.549+
