y+=+4x%5E2+%2B+16x+%2B+23
Use quadratic formula
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
x+=+%28-16+%2B-+sqrt%28+16%5E2-4%2A4%2A23+%29%29%2F%282%2A4%29+
x+=+%28-16+%2B-+sqrt%28+256+-+368+%29%29%2F8+
x+=+%28-16+%2B-+sqrt%28+-112+%29%29%2F8+
x+=+-2+%2B+10.583%2Ai+%2F+8+ and
x+=+-2+-+10.583%2Ai+%2F+8+
------------------------
simplified
x+=+-2+%2B+1.323%2Ai
x+=+-2+-+1.323%2Ai
