subtract %286y%5E2-4y-2%29 from the sum of %282y%5E2%2B2%29 and %284y%2B7%29

first find the sum+of %282y%5E2%2B2%29+and+%284y%2B7%29
%282y%5E2%2B2%29+%2B+%284y%2B7%29=2y%5E2%2B2%2B+4y%2B7=2y%5E2%2B+4y%2B9

now subtract %286y%5E2-4y-2%29 from 2y%5E2%2B+4y%2B9

2y%5E2%2B+4y%2B9-%286y%5E2-4y-2%29
=2y%5E2%2B+4y%2B9-6y%5E2%2B4y%2B2
=-4y%5E2%2B+8y%2B11
