Question

Place these numbers in correct order and and simplify 25x^2 +6x^3 -7 +17 -24x^4 +6

Answer 1

Answer:

$-24x^4+6x^3+25x^2+16$

Step 1:

We need to place the numbers in descending order of the power. Here, $-24x^4$ has the largest power, so that number goes first. We keep doing this until we end up with our final expression, placed in order based on the powers.

$-24x^4+6x^3+25x^2+17-7+6$

Step 2:

We can see that the last three numbers, 17, -7, and 6, don't have variables or powers, so we simplify by adding (and subtracting) them.

$17-7=10\\10+6=16$

Our final equation:

$-24x^4+6x^3+25x^2+16$
