Question

A2 (a+3)-2a (a-3) упростить выражение

Answer 1

(a+3)-2a(a-3)=a+3-2a*a-2a*(-3)=a+3-2a²+6a=-2a²+7a+3  Ответ: -2a²+7a+3

Answer 2

To simplify the expression A2(a + 3) - 2a(a - 3), we'll start by applying the distributive property and then combine like terms:

1. Distributive Property: A2(a + 3) - 2a(a - 3) = A2 * a + A2 * 3 - 2a * a + 2a * 3

2. Combine Like Terms: Now let's simplify the terms: A2 * a = A2a A2 * 3 = 3A2 -2a * a = -2a^2 (Multiplying -2a with 'a' gives us -2a^2) 2a * 3 = 6a (Multiplying 2a with 3 gives us 6a)

Putting it all together: A2(a + 3) - 2a(a - 3) simplifies to: A2a + 3A2 - 2a^2 + 6a

So, the simplified expression is: A2a + 3A2 - 2a^2 + 6a
