For the polynomial 8y43y2+1a. Is it a monomial binomial, or trinomial? b. What is its degree?

Why does (a+b)2result in a trinomial. but (a+b)(ab)result in a binomial?

How do you determine whether to use plus or minus signs in the binomial factors of a trinomial of the form x2+bx+c where b and c may be positive or negative numbers?

Multiply using the Binomial Squares pattern: (25i)2.
