Question

8x3 + 20x²y - 50xy2 - 125y3

Answer 1

8x3+20x2y-50xy2-125y3

Final result :

8x3 + 20x2y - 50xy2 - 125y3

Step by step solution :

Step 1 :

Equation at the end of step 1 :

(((8•(x3))+((20•(x2))•y))-(50x•(y2)))-53y3

Step 2 :

Equation at the end of step 2 :

(((8•(x3))+((20•(x2))•y))-(2•52xy2))-53y3

Step 3 :

Equation at the end of step 3 :

(((8•(x3))+((22•5x2)•y))-(2•52xy2))-53y3

Step 4 :

Equation at the end of step 4 :

((23x3 + (22•5x2y)) - (2•52xy2)) - 53y3

Step 5 :

Checking for a perfect cube :

5.1 8x3+20x2y-50xy2-125y3 is not a perfect cube

Final result :

8x3 + 20x2y - 50xy2 - 125y3
