Find the sum. Write your answer in standard form.

(4x3 + 2x + 6) + (2x3 - x? + 2)

The sum is

(4x3+2x+6) + (2x3-x2+2)

Final result:

6x3 - x2 + 2x + 8

Reformatting the input:

Changes made to your input should not affect the solution:

(1) : "x2" was replaced by "x^2". 2 more similar replacement (s).

Step by step solution:

Step 1:

Equation at the end of step 1:

(((4• (x3)) + 2x) + 6) + ((2x3-x2) + 2)

Step 2:

Equation at the end of step 2:

((22x3 + 2x) + 6) + (2x3 - x2 + 2)

Step 3:

Checking for a perfect cube:

3.1 6x3-x2+2x+8 is not a perfect cube

Trying to factor by pulling out:

3.2 Factoring: 6x3-x2+2x+8

Thoughtfully split the expression at hand into groups, each group having two terms:

Group 1: 2x+8

Group 2: 6x3-x2

Pull out from each group separately:

Group 1: (x+4) • (2)

Group 2: (6x-1) • (x2)
