Question

2а(а-в) (а-в)(а+в) (3а-2)(2а+4) (3-х)(х+4)+х^2

Answer 1

2а * (а - в)  = 2а² - 2ав,

(а - в)(а + в)  = а² + ав - ав - в² = а² - в²,

(3а - 2)(2а + 4)  = 6а² + 12а - 4а - 8 = 6а² - 8а - 8,

(3 - х)(х + 4) + х² = 3х + 12 - х² - 4х + х² = 12 - х

Answer 2

Let's simplify the expression step by step:

1. 2а(а-в) = 2a^2 - 2av
2. (а-в)(а+в) = a^2 - в^2
3. (3а-2)(2а+4) = 6a^2 + 12а - 4а - 8 = 6a^2 + 8а - 8
4. (3-х)(х+4) = 3x + 12 - x^2 - 4x = -x^2 - x + 12
5. Finally, add the term х^2.

Now, let's put all the simplified expressions together:

2a(а-в) (а-в)(а+в) (3а-2)(2а+4) (3-х)(х+4) + х^2 = (2a^2 - 2av)(a^2 - в^2)(6a^2 + 8a - 8)(-x^2 - x + 12) + х^2

Since there is no further specified information or simplification requirement, this is the simplified expression.
