    (7x3+2x2-2)-(4x3+7x+8) Final result : 3x3 + 2x2 - 7x - 10 Reformatting the input : Changes made to your input should not affect the solution: (1): "x3" was replaced by "x^3". 2 more similar replacement(s). Step by step solution : Step 1 : Raise x to the 3rd power Exponentiaion : Equation at the end of step 1 : (((7•(x3))+(2•(x2)))-2)-(((4•x3)+7x)+8) Step 2 : Raise x to the 2nd power Exponentiaion : Equation at the end of step 2 : (((7•(x3))+(2•x2))-2)-(4x3+7x+8) Step 3 : Raise x to the 3rd power Exponentiaion : Equation at the end of step 3 : (((7 • x3) + 2x2) - 2) - (4x3 + 7x + 8) Step 4 : Simplify 7x3+2x2-2 - 4x3+7x+8 Checking for a perfect cube : 4.1 3x3+2x2-7x-10 is not a perfect cube Trying to factor by pulling out : 4.2 Factoring: 3x3+2x2-7x-10
