Answer: 2x^2 - 4x + 8

Step-by-step explanation:

The first step to solving this equation will be to distribute the negative sign to the 4x and the -3 in parenthesis.

-1(4x - 3) = -4x + 3

We now have the equation:

2x^2 + 5 -4x + 3

Combine like terms:

2x^2 - 4x + 8

-5+7q+ -5q+ -9q please help

vekshin1

For this case we must simplify the following expression

$-5 + 7q + (- 5q) + (- 9q)$

We know that, by definition:

$+ * - = -$

So, rewriting the expression we have:

$-5 + 7q-5q-9q =$

We add similar terms taking into account that:

Equal signs are added and the same sign is placed.

Different signs are subtracted and the major's sign is placed:

$-5 + 2q-9q =\\-5-7q$

Answer:

$-5-7q$
