Answer:
-a² + 2ab + b² is your answer, or C).
Step-by-step explanation:
b(a + b) -a (a - b)
Distribute b to (a + b), and -a to (a - b)
b(a + b) = ab + b²
-a(a - b) = -a² + ab
Simplify. Combine like terms.
(-a² + ab) + (ab + b²) = -a² + 2ab + b²
-a² + 2ab + b² is your answer, or C).

Answer: 2 3/4
Step-by-step explanation: 1/4 + 3/4 is 1 whole plus 1/4+1/4 would equal the 1/2 you need.

We need to add 2 more to get to 4 1/2
So the answer would be 2 3/4
2 3/4 + 1 3/4 = 4 1/2
