Polynomial Long Division 17x^3 - 22x + 7x^4 + 24 - 47x^2 and 7x-4 MathCelebrity logo Image to Crop Using polynomial long division, evaluate the expression below:
17x3 - 22x + 7x4 + 24 - 47x2
7x - 4

First, we write our expression in long division format and follow the steps below.
Step 1
 1a)  Divide the first term of the dividend by the first term of the divisor → 7x4 ÷ 7x = 1x(4 - 1) = x3
 1b)  We multiply that part of the quotient by the divisor → x3(7x - 4) = 7x4 - 4x3  →  Click here to see the Math for this Multiplication.
 1c)  Subtract 7x4 - 4x3 from 7x4 + 17x3 - 47x2 - 22x + 24 to get 21x3 - 47x2 - 22x + 24  →  Click here to see the Math.
      x3
7x - 47x4 + 17x3 - 47x2 - 22x + 24
   7x4 - 4x3              21x3 - 47x2 - 22x + 24   

Step 2
 2a)  Divide the first term of the dividend by the first term of the divisor → 21x3 ÷ 7x = 3x(3 - 1) = 3x2
 2b)  We multiply that part of the quotient by the divisor → 3x2(7x - 4) = 21x3 - 12x2  →  Click here to see the Math for this Multiplication.
 2c)  Subtract 21x3 - 12x2 from 21x3 - 47x2 - 22x + 24 to get -35x2 - 22x + 24  →  Click here to see the Math.
      x3 + 3x2
7x - 47x4 + 17x3 - 47x2 - 22x + 24
   7x4 - 4x3              21x3 - 47x2 - 22x + 24        21x3 - 12x2              -35x2 - 22x + 24   

Step 3
 3a)  Divide the first term of the dividend by the first term of the divisor → -35x2 ÷ 7x = -5x(2 - 1) = -5x
 3b)  We multiply that part of the quotient by the divisor → -5x(7x - 4) = -35x2 + 20x  →  Click here to see the Math for this Multiplication.
 3c)  Subtract -35x2 + 20x from -35x2 - 22x + 24 to get -42x + 24  →  Click here to see the Math.
      x3 + 3x2 - 5x
7x - 47x4 + 17x3 - 47x2 - 22x + 24
   7x4 - 4x3              21x3 - 47x2 - 22x + 24        21x3 - 12x2              -35x2 - 22x + 24          -35x2 + 20x              -42x + 24   

Step 4
 4a)  Divide the first term of the dividend by the first term of the divisor → -42x ÷ 7x = -6x(1 - 1) = -6
 4b)  We multiply that part of the quotient by the divisor → -6(7x - 4) = -42x + 24  →  Click here to see the Math for this Multiplication.
 4c)  Subtract -42x + 24 from -42x + 24 to get   →  Click here to see the Math.
      x3 + 3x2 - 5x - 6
7x - 47x4 + 17x3 - 47x2 - 22x + 24
   7x4 - 4x3              21x3 - 47x2 - 22x + 24        21x3 - 12x2              -35x2 - 22x + 24          -35x2 + 20x              -42x + 24            -42x + 24                  

Since we do not have a remainder, we have our answer below:
Answer = x3 + 3x2 - 5x - 6

Answer = x3 + 3x2 - 5x - 6
