(2x^3+6x-1)+(3x^2-7x)

sattari [20]

For this case we must simplify the following expression:

$(2x ^ 3 + 6x-1) + (3x ^ 2-7x)$

We eliminate the parentheses taking into account that:

$+ * + = +\\+ * - = -$

So, we have:

$2x ^ 3 + 6x-1 + 3x ^ 2-7x =$

We add similar terms taking into account that:

Different signs are subtracted and the sign of the major is placed:

$2x ^ 3 + 3x^2-x-1$

Answer:

$2x ^ 3 + 3x^2-x-1$

6x + 2x - 1 = 5x + 11

sammy [17]

6x + 2x - 1 = 5x + 11
      8x - 1 = 5x + 11
      - 5x    - 5x
      3x - 1 = 11
      + 1   + 1
   3x = 12
      3 3
