anonymous · Answer

15x^3 - 5x^2 - 6x^2 -2 + 2

is this right?

anonymous · Answer

-x + 2

anonymous · Answer

15^3 - 11x^2 - x + 2 ?

anonymous · Answer

the five
so it would have a + 7

jusaquikie · Answer

standard form just means the higher order goes to the left, so collect all the orders of X and then simplify and sort greatest to least ie X^5 +X^4 + X^3 +X^2 + X + 5

anonymous · Answer

so:

1. 12x^3 + 5 - 5x^2 - 6x^2 + 3x3 + 2 - x

2. 12x^3 + 3x^3 5 - 5x^2 - 6x^2 + 5 + 2 - x

3. 12x^3 + 3x^3 5 - 5x^2 - 6x^2 - x + 2 + 5

4. 15x^3 - 11x^2 - x + 7

anonymous · Answer

What you did was right.

jusaquikie · Answer

12x^3 + 5 - 5x^2 - 6x^2 + 3x^3 + 2 - x
So
$$(12+3)x^3+((-5)+(-6))x^2 +(-1)x + (5+2)$$
