Factors are (7y - 3)(7y - 2) so it's not a perfect square.

A cubic trinomial is an algebraic expression with three terms, where the highest power of the variable is 3. For example, (x^3 + 2x^2 - 3x) is a cubic trinomial. If the expression you're referring to fits this criteria, then yes, it is a cubic trinomial.
Factors are (7y - 3)(7y - 2) so it's not a perfect square.
To find the factors of the trinomial (3m^2 + 11mn + 6n^2), we need to break it down into two binomials. First, we find two numbers that multiply to the product of the leading coefficient and constant term, which are (3 \times 6 = 18). Then, we look for two numbers that add up to the middle coefficient, which is 11. The factors are ((3m + 2n)(m + 3n)).
