Step-by-step explanation:
The polynomial has two terms : x³ and 42
It is divided by x-4 with has two terms : x-4
The numerator is : x³ +42 and the denominator is x-4
When dividing use long division method where:
- You divide the first term of the numerator with the first term of the denominator and put that in the answer, then multiply the denominator by that answer and put the value below the numerator followed by subtraction to create a new polynomial.Repeat the steps using the new polynomial
In this case, it will be;
x-4√x³+42 -----------------divide x³ by x to get x² then multiply the denominator to get
x³-42
x³-4x² ----------perform subtraction to get
0-4x²-42--------new polynomial to be divided by x-4 to get -4x
-4x²+16x---------multiply the answer -4x by the denominator to get this
16x-42 ---------perform subtraction, the new polynomial to be divided by x-4 to get 16
16x-64-----------perform subtraction to get 22 as the remainder
The answer will be ; quotient x²-4 and the remainder is 22/x-4 which is
