4x^3-11x^2-54x+45/x-5
We have to do a long division here, dividing (x - 5) into 4x^3 - 11x^2 - 54x + 45
4x^2 + 9x – 9
--------------------------------
x – 5 ) 4x^3 – 11x^2 – 54x + 45
4x^3 – 20x^2
===========
9x^2 – 54x
9x^2 – 45x
=========
– 9x + 45
– 9x + 45
========
----------
Answer: 4x^3 – 11x^2 – 54x + 45 divided by (x – 5) is: 4x^2 + 9x – 9
