"Whats The Answer Of ( 7ab - B2 ) - ( 5a2 + Ab + B2 ) ?"

Whats the answer of ( 7ab - b2 ) - ( 5a2 + ab + b2 ) ?

 

Answer:

-5a²+8a

Step-by-step explanation:

• Combine the terms (7ab-b²-5a²+ab+b²)
• Combine the similar terms (7ab+ab), (-b²+b²), (-5a²) : Since -5a² has no other terms, just copy it.
• Add the terms (8ab), (0); since b² will subtract b², so the answer is 0, (-5a²)
• ( 7ab - b² ) - ( 5a² + ab + b² ) = -5a²+8a
• Note: do not copy the 0 since the coefficients are the same terms but different operations.
