Answer:
2 ( 4x² + 3xy - 2 )
Step-by-step explanation:
( 5x² + 4xy - 7 ) + ( 3x² + 2xy + 3 )
5x² + 4xy - 7 + 3x² + 2xy + 3
Combine like terms.
5x² + 3x² + 4xy + 2xy - 7 + 3
8x² + 6xy - 4
Factorize the answer.
2 ( 4x² + 3xy - 2 )

Step-by-step explanation:
This is a matrices. Since they are both the same in format, we can add them together. But first we must multiply each value by the given values.
1.
![\left[\begin{array}{ccc}-30 & -5 \\ 20 & 30 \\ -35 & 35 \end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D-30%20%26%20-5%20%5C%5C%2020%20%26%2030%20%5C%5C%20-35%20%20%26%2035%20%5Cend%7Barray%7D%5Cright%5D)
