Answer:
z3 + z2 + 5z - 3
Explanation:
Step 1 :
Equation at the end of step 1 :
(((((z3)+5z)+(3•(z2)))+1)-4)-2z2
Step 2 :
Equation at the end of step 2 :
(((((z3)+5z)+3z2)+1)-4)-2z2
Step 3 :
Checking for a perfect cube :
3.1 z3+z2+5z-3 is not a perfect cube
Trying to factor by pulling out :
3.2 Factoring: z3+z2+5z-3
Thoughtfully split the expression at hand into groups, each group having two terms :
Group 1: 5z-3
Group 2: z3+z2
Pull out from each group separately :
Group 1: (5z-3) • (1)
Group 2: (z+1) • (z2)
