Question

the given expression is equivalent to z³-144z​

Answer 1

Answer:

z(z-12)(z+12)

Step-by-step explanation:

z³-144z

we will take out z as it is common in both

z(z²-144)

now we will take square out of both the terms which are inside the bracket

the z² will become (z)² and the 144 will become (12)²

z{(z)²-(12)²}

now we will use the formula of a²-b² =(a-b)(a+b)

z(z-12)(z+12)

PROOF

z(z-12)(z+12)

first we will multiple the z with the term (z-12)

(z²-12z)(z+12)

now multiple z²-12z with the term (z+12)

z³-144z

hence proofed
