the binomial y to the power of 2 - 49 has y - 7 as one of its factors.
what is the other factor of the binomial?
To find the other factor of the binomial, we can use the difference of squares formula.
The difference of squares formula states that if we have a binomial in the form x^2 - a^2, its factors are (x - a) and (x + a).
In this case, the binomial is y^2 - 49, which can be written as (y)^2 - (7)^2.
Using the difference of squares formula, we can factor the binomial as (y - 7)(y + 7).
Therefore, the other factor of the binomial is (y + 7).
