Question 1

What is the simplified expression for 3a²+9ab+5-4a²-4ab+3

Question 2

Answer:

5ab + 8 - 1a^2.

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

Question 3

Answer:

-
${a}^(2) + 5ab + 8$

solution,

$3 {a}^(2) + 9ab + 5 - 4 {a}^(2) - 4ab + 3$

collect like terms:

$3 {a}^(2) - 4 {a}^(2) + 9ab - 4ab + 5 +3$

Simplify:

$- {a}^(2) + 5ab + 8$

hope this helps ..

Good luck on your assignment..
