Question

Which polynomial is equivalent to (z+3)^2

Answer 1

z-3/z+3-z-9/z2+3z

Final result :

3 • (z3 + z2 - z - 3)

———————————

z2

Explanation:

Step 1 :

9

Simplify ——

z2

Equation at the end of step 1 :

3 9

((((z-—)+3)-z)-——)+3z

z z2

Step 2 :

3

Simplify —

z

Equation at the end of step 2 :

3 9

((((z - —) + 3) - z) - ——) + 3z

z z2

Step 3 :

Rewriting the whole as an Equivalent Fraction :

3.1 Subtracting a fraction from a whole

Rewrite the whole as a fraction using z as the denominator :

z z • z

z = — = ——

1 z
