select the correct answer.\nwhat is the factored form of $b^{3}-1,000$?\na. $(b + 10)(b^{2}-10b + 100)$\nb. $(b - 10)(b^{2}+10b + 100)$\nc. $(b - 10)(10b^{2}+b + 100)$\nd. $(b + 10)(10b^{2}-b + 100)$
Answer
Explanation:
Step1: Recall the difference - of - cubes formula
The difference - of - cubes formula is $a^{3}-b^{3}=(a - b)(a^{2}+ab + b^{2})$. In the expression $b^{3}-1000$, we have $a = b$ and $b = 10$ since $1000=10^{3}$.
Step2: Apply the formula
Substitute $a = b$ and $b = 10$ into the formula $a^{3}-b^{3}=(a - b)(a^{2}+ab + b^{2})$. We get $b^{3}-10^{3}=(b - 10)(b^{2}+10b + 100)$.
Answer:
B. $(b - 10)(b^{2}+10b + 100)$
