Answer:
Quotient = x^ -1 and the remainder: 0
Step-by-step explanation:
Constant to the left with the opposite sign and coefficients to the right:
-5 | 1 5 -1 -5
Make an horizontal line
Bring down the first coefficient (1) under the line.
Multiply the constant -5 times 1=-5 and add -5 to 5 = 0
Keep doing the same with the coefficients.
Answer: that;s is no solution
