<span>We can expand this expression using foil method (first, then out, then in then last), multiply them together: (y+5)(y+7) y^2 + 7y + 5y + 35 y^2 + 12y + 35
This is already simplified and thus is also the final answer. There are also other ways but foil method is the easiest.</span>
(y + 5)(y + 7) use FOIL F -- multiply first terms in each set....y * y = y^2 O -- multiply outside terms in each set...y * 7 = 7y I -- multiply inside terms in each set...5 * y = 5y L -- multiply last terms in each set...5 * 7 = 35 now put them all together... y^2 + 7y + 5y + 35 --- combine like terms y^2 + 12y + 35 <-- ur answer
