Question

2. Impoename ssipaxenne. 1) 12²-(4-3) (3a + 1) = 2) 56x² + (14x-1)(2-4x) =​

Answer 1

Ответ:

1) 12²-(4-3)(3а+1) =144-1(3а+1)=144-(3а+1)=144-3а-1=143-3а

2) 32х-2

Answer 2

It appears you've provided two mathematical expressions, and I'll help you simplify them:

1. $12^2 - (4 - 3)(3a + 1)$

Let's simplify this step by step:

$12^2$ is equal to 144.

Now, let's simplify the second part of the expression: $(4 - 3)(3a + 1)$

$4 - 3$ is equal to 1, and the expression becomes $1(3a + 1)$, which is simply $3a + 1$.

Now, you can subtract $3a + 1$ from 144:

$144 - (3a + 1) = 143 - 3a$

So, the simplified expression is $143 - 3a$.

2. $56x^2 + (14x - 1)(2 - 4x)$

Let's simplify this one as well:

First, let's distribute the second term $(14x - 1)$ across the terms in the second parentheses:

$56x^2 + 14x(2) - 14x(4x) - 1(2) + 1(4x)$

Now, perform the multiplications:

$56x^2 + 28x - 56x^2 - 2 + 4x$

Now, simplify the expression by combining like terms:

The $56x^2$ and $-56x^2$ terms cancel out.

You're left with:

$28x - 2 + 4x$

Combine the x-terms:

$32x - 2$

So, the simplified expression is $32x - 2$.
