Answer:

  • [tex]\boxed{\sf{7p^2+13q^2-4p}}[/tex]

Step-by-step explanation:

First, you have to find the combine like terms use the distributive property.

Distributive property:

  • A(B+C)=AB+AC
  • A(B-C)=AB-AC

Add the numbers from left to right.

[tex]\sf{9q^2+4q^2=13q^2}[/tex]

[tex]\Longrightarrow \boxed{\sf{7p^2+13q^2-4p}}}[/tex]

Therefore, the final answer is 7p²+13q²-4p.

I hope this helps, let me know if you have any questions.
