### Related Information

Question:

\([(7 y^2+3xy-9)\) - \((2 y^2+3xy-5)] \)

A
\([5 y^2-4]\)

explanation

When subtracting polynomials the first step is to distribute the negative sign through the parentheses. This changes the sign on each term inside the parentheses:

\([7 y^2+3xy-9- 2y^2-3xy+5]\)

Arrange like terms next to each other (optional):

\([7 y^2-2 y^2 +3xy-3xy-9+5]\)

Combine like terms to compute the answer: \([5 y^2-4] \).

Pretty good for learning basic stuff. Just wish the equation would change up so you don't just remember the answer.
