Divide 14x3 − 21x2 − 7x by −7x

Answer 1

We can use long division to divide 14x3 − 21x2 − 7x by −7x:

```
-2x2 + 3x + 1
__________
-7x | 14x^3 - 21x^2 - 7x + 0
-14x^2 + 21x^2
--------------
0 - 7x
- (0 - 7x)
----------
0
```

Therefore, 14x3 − 21x2 − 7x divided by −7x is equal to −2x2 + 3x + 1.

Answer 2

Divide 18a6b2 by 9a3b

Answer 3

We can use the quotient rule to divide 18a6b2 by 9a3b:

```
18a6b2 ÷ 9a3b = (18 ÷ 9)(a6 ÷ a3)(b2 ÷ b)
= 2a6-3b1
= 2a3b
```

Therefore, 18a6b2 divided by 9a3b is equal to 2a3b.
