Use synthetic division to find (x^2+3x–4)÷(x+4)

X^2-x- 8/x+4

Step-by-step explanation:

X+4 becomes a negative 4

Then multiply -4 by the first number which is 1 so -4×1 is -4. Then subtract -4 by the second number 3. This gives you -1 so multiply that by 4 which is -4. Then subtract 4 from the third number -4. So that'll give you -8. Then add an x-value to every number except the very last number as that number will be you remainder.

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1
