Answer:
Answer is A on edg
Second question is B
Step-by-step explanation:
The choice which shows the sum of the polynomials rewritten with like terms grouped together is; [3a2 + (–3a2)] + (–5ab + 8ab) + (b2 + 2b2)
Grouping Like Algebraic terms
By observation, 3 categories of terms are common to both expressions whose sum is to be computed.
The expressions are;
- (3a² – 5ab + b²) and (–3a² + 2b² + 8ab)
By adding each term in parentheses in which case, like terms are added together, we have;
- [3a2 + (–3a2)] + (–5ab + 8ab) + (b2 + 2b2)
