Subtraction of algebraic expressions are explained in each steps:

**Steps I:** Arrange the terms of the given expressions in the same order.

**Steps II:** Write the given expressions in two rows in such a way that the like terms occur one below the other, keeping the expression to be subtracted in the second row.

**Steps III:** Change the sign of each term in the lower row from + to - and from - to +.

**Steps IV:** With new signs of the terms of lower row, add column wise.

**1. Subtract 4a + 5b - 3c from 6a - 3b + cSolution: **

6a - 3b + c

+ 4a + 5b - 3c

(-) (-) (+)

_____________

2a - 8b + 4c

_____________

**2. Subtract 3x² - 6x - 4 from 5 + x - 2x².
Solution: **

Arranging the terms of the given expressions in descending powers of x and subtracting column-wise;

- 2x² + x + 5

+ 3x² - 6x - 4

(-) (+) (+)

_____________

- 5x² + 7x + 9

_____________

**3. Subtract 3x + y – 3z from 9x – 5y + z
Solution: **

9x – 5y + z

+ 3x + y – 3z

(-) (-) (+)

_____________
