Answer:
5x4 - 3x2 + 9x - 7
Step-by-step explanation:
Step by step solution :
Step 1 :
Equation at the end of step 1 :
(((5•(x4))+7x)+2)-((3x2-2x)+9)
Step 2 :
Equation at the end of step 2 :
((5x4 + 7x) + 2) - (3x2 - 2x + 9)
Step 3 :
Checking for a perfect cube :
3.1 5x4-3x2+9x-7 is not a perfect cube
Trying to factor by pulling out :
3.2 Factoring: 5x4-3x2+9x-7
