Sum of 4x^3+2x^2-4x+3 and 7x^3-4x+7x+8

Equation at the end of step 1 : (((7• (x3)) + (2• (x2))) - 2) - ((22x3+7x) + 8) Step 2 : Equation at the end of step 2 : (((7• (x3)) + 2x2) - 2) - (4x3+7x+8) Step 3 : Equation at the end of step 3 : ((7x3 + 2x2) - 2) - (4x3 + 7x + 8) Step 4 : 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

Thoughtfully split the expression at hand into groups, each group having two terms : Group 1: - 7x-10

Group 2: 3x3+2x2

Pull out from each group separately:

Group 1: (7x+10) • (-1)

Group 2: (3x+2) • (x2)
