Answer 1

Ответ:

(3а-4)(2+2а)=6а-6а²+8+8а = 6а²-2а-8

Answer 2

Привет!)

$(3a-4)(2+2a)=6a+6a^{2} -8-8a=6a^{2} -2a-8$

Answer 3

To expand the expression (3a - 4) * (2 + 2a), you can use the distributive property (FOIL). Here's the step-by-step expansion:

(3a - 4) * (2 + 2a)

First, you can multiply each term in the first expression by each term in the second expression:

(3a * 2) + (3a * 2a) + (-4 * 2) + (-4 * 2a)

Now, simplify each term:

6a + 6a^2 - 8 - 8a

Finally, combine like terms:

(6a - 8a) + 6a^2 - 8

-2a + 6a^2 - 8

So, the expanded expression is 6a^2 - 2a - 8.
