Answer 1

Answer:

• $\boxed{\sf{7p^2+13q^2-4p}}$

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.

$\sf{9q^2+4q^2=13q^2}$

$\Longrightarrow \boxed{\sf{7p^2+13q^2-4p}}}$

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