Subtract the following, 4ab2 from 3ab2 , 7a-3b from 4a-2b , 9pq2+4pq from 5pq2-4pq , (8x3y+6xy2) from (5x3y-2xy2) , 6+2a-3a2 from -5+9a-2a2 , x3-y3+xy2 from 2x3-3y3-4xy2 , 15m2n2+5mn-4 from 14m2n2+5mn-4 , 7x2y3-2xy3+3x2y from 6x2y+4xy3-2x2y3 , 2a3-4b3+c3 from 5a3-3c3+3b3

To solve these subtraction problems, we'll subtract each term in the second expression from the corresponding term in the first expression. This involves distributing the negative sign and combining like terms. Let's solve them step-by-step:

### 1. Subtract \(4ab^2\) from \(3ab^2\)

\[
3ab^2 - 4ab^2 = -ab^2
\]

### 2. Subtract \(7a - 3b\) from \(4a - 2b\)

\[
(4a - 2b) - (7a - 3b) = 4a - 2b - 7a + 3b = -3a + b
\]

### 3. Subtract \(9pq^2 + 4pq\) from \(5pq^2 - 4pq\)

\[
(5pq^2 - 4pq) - (9pq^2 + 4pq) = 5pq^2 - 4pq - 9pq^2 - 4pq = -4pq^2 - 8pq
\]

### 4. Subtract \((8x^3y + 6xy^2)\) from \((5x^3y - 2xy^2)\)

\[
(5x^3y - 2xy^2) - (8x^3y + 6xy^2) = 5x^3y -
