Question

Some steps to rewrite the expression x3 − 16x + x2 − 16 as a product of three factors are shown below:

Answer 1

Answer:

third one

Step-by-step explanation:

the third one should be the answer

step 4 came out becoz of taking the common factor(x+1) and combining x2 and (-16)

Step 5 came out becoz of the theory of (a^2-b^2) = (a+b)(a-b)

ps 16 here is equal to 4^2
