Question

Simplify z3+5z+3z2+1-4-2z2

Answer 1

Answer:

z3 + z2 + 5z - 3

Step-by-step 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)
