Question

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

Answer 1

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)
