b. Dividing 5x by (x + 4)
c. Adding 5x to (x + 4)
d. Multiplying 5x by (x + 4)
Dividing Polynomials:
Long Division:
In dividing 5x² + 14x – 24 by x + 4, to obtain the second line the process is to multiply 5x by x + 4.
Solution:
5x - 6
x + 4 √ 5x² + 14x - 24
5x² + 20x
-6x – 24
-6x – 24
0
- Divide 5x² by x.
- Multiply the obtained answer with x + 4.
- Subtract the second line 5x² + 20x from the first line 5x² + 14x – 24 to obtain the third line of the long division process.
- Divide -6x with x.
- Multiply the obtained answer with x to obtain the fourth line of the long division.
- Subtract the fourth line from the third line. Write 0 to show that the division is done.
Definition:
