    okay so first you need to distribute the negative that's outside the first set of parentheses

    I showed you the FOIL method so what do you get when you multiply the FIRST terms from the 2 brackets together?

    Well - that is the two LAST terms - but its OK - we need that as well so the OUTER terms are 7y and 4 the inner terms are 6 and 5y so what do you get when you multiply THOSE pairs?

    so the 2 brackets altogether are 35y^2 +27y + 30y + 24 we need to join the 2 terms with y in AND THEN REMEMBER THE - sign so first join the two y terms...

    it's 35y^2 +58 y + 28 OK but we also have the minus sign outside ALL so -(35y^2 +58 y + 28 ) so now distribute the minus inside the bracket and you will have th eanswer (AND you did it YOURSELF!) well done
