It's please, first off.
P%5E2=3%2B13P
P%5E2-13P-3=0
Use the quadratic formula,
P+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
P+=+%28-%28-13%29+%2B-+sqrt%28+%28-13%29%5E2-4%2A1%2A%28-3%29+%29%29%2F%282%2A1%29+
P+=+%2813+%2B-+sqrt%28+169%2B12+%29%29%2F%282%29+
P+=+%2813+%2B-+sqrt%28181%29+%29%2F%282%29+
