Answer:
5ab + 8 - 1a^2.
Step-by-step explanation:
Combining like terms, we get 3a^2 - 4a^2 = -1a^2. We get 9ab - 4ab = 5ab. Then we get, 5 + 3 = 8. Together this is 5ab + 8 - 1a^2
Answer:
-[tex] {a}^{2} + 5ab + 8[/tex]
solution,
[tex]3 {a}^{2} + 9ab + 5 - 4 {a}^{2} - 4ab + 3[/tex]
collect like terms:
[tex]3 {a}^{2} - 4 {a}^{2} + 9ab - 4ab + 5 +3[/tex]
Simplify:
[tex] - {a}^{2} + 5ab + 8[/tex]
hope this helps ..
Good luck on your assignment..
