answer please

Answer:

-3a^2 + 2a + 16

Step-by-step Explanation:

(8 - 3a)(2 + a) is the same as (-3a + 8)(a + 2). The answer is still the same but if the variables are found in the last and outer terms, you should arrange the terms in your final answer.

(8 - 3a)(2 + a)

(8)(2) + (8)(a) + (-3a)(2) + (-3a)(a)

16 + 8a + -6a - 3a^2

16 + 2a - 3a^2

It is still correct but it would be better to arrange it. The variable with the highest exponent should be first followed by the variable with no exponent then the last will be the constant.

= -3a^2 + 2a + 16
