Use long division to divide 4x3 l8x2 1x 20 devide x4 4x23

Use long division to divide. (4x^3 - l8x^2 + 1x + 20) devide (x-4) 4x^2-34x+137-528/x-4 4x^2-2x-7-8/x-4) 4x^2 - 2x-15 4x^2-34x-391

Solution

4x² - 2x - 7

----------------------------

x - 4 4x³ - 18x² + x + 20

4x³ - 16x²

   ^{----------------------------}

  -2x² + x + 20

-2x² + 8x

---------------------------------

-7x + 20

-7x + 28

----------------------------------

-8
