x4-2x3-10x2+7x+4x4−2x3−10x2+7x+4 , x-2
Step 1
Step 1.1
Place the numbers representing the divisor and the dividend into a division-like configuration.
2 | 1 | -2 | -10 | 7 | 4 |
Step 1.2
The first number in the dividend (1) is put into the first position of the result area (below the horizontal line).
2 | 1 | -2 | -10 | 7 | 4 |
1 |
Step 1.3
Multiply the newest entry in the result (1) by the divisor (2) and place the result of (2) under the next term in the dividend (-2).
2 | 1 | -2 | -10 | 7 | 4 |

1 |
Step 1.4
Add the product of the multiplication and the number from the dividend and put the result in the next position on the result line.
2 | 1 | -2 | -10 | 7 | 4 |
2 | |||||
1 | 0 |
Step 1.5
Multiply the newest entry in the result (0) by the divisor (2) and place the result of (0) under the next term in the dividend (-10).
2 | 1 | -2 | -10 | 7 | 4 |
2 | 0 | ||||
1 | 0 |
Step 1.6
Add the product of the multiplication and the number from the dividend and put the result in the next position on the result line.
2 | 1 | -2 | -10 | 7 | 4 |
2 | 0 | ||||
1 | 0 | -10 |
Step 1.7
Multiply the newest entry in the result (-10) by the divisor (2) and place the result of (-20) under the next term in the dividend (7).
2 | 1 | -2 | -10 | 7 | 4 |
2 | 0 | -20 | |||
1 | 0 | -10 |
Step 1.8
Add the product of the multiplication and the number from the dividend and put the result in the next position on the result line.
2 | 1 | -2 | -10 | 7 | 4 |
2 | 0 | -20 | |||
1 | 0 | -10 | -13 |
Step 1.9
Multiply the newest entry in the result (-13) by the divisor (2) and place the result of (-26) under the next term in the dividend (4).
2 | 1 | -2 | -10 | 7 | 4 |
2 | 0 | -20 | -26 | ||
1 | 0 | -10 | -13 |
Step 1.10
Add the product of the multiplication and the number from the dividend and put the result in the next position on the result line.
2 | 1 | -2 | -10 | 7 | 4 |
2 | 0 | -20 | -26 | ||
1 | 0 | -10 | -13 | -22 |
Step 1.11
All numbers except the last become the coefficients of the quotient polynomial. The last value in the result line is the remainder.
1x3+0x2+(-10)x-13+-22x-2
Step 1.12
Simplify the quotient polynomial.
x3-10x-13-22x-2
x3-10x-13-22x-2
Step 2
The remainder from dividing x4-2x3-10x2+7x+4x-2 is -22, which is not equal to 0. The remainder is not equal to 0 means that x-2 is not a factor for x4-2x3-10x2+7x+4.
x-2 is not a factor for x4-2x3-10x2+7x+4
