Question

Which equation is related to (squ)x+10)-1?

Answer 1

  (x + 10)² - 1

= (x² + 20x + 100) - 1

= x² + 20x + 99

None of the choices you provided are correct. Did you type in the question wrong?

Answer 2

Answer:

None of the above.

Step-by-step explanation:

The given expression is

$(x+10)^{2}-1$

To solve this expression, we first need to solver the power of the binomial with the following formula

$(a+b)^{2}=a^{2}+2ab+b^{2}$

Where $a=x$ and $b=10$, so

$(x+10)^{2}-1=x^{2} +2(x)(10)+10^{2}-1=x^{2} +20x+100-1\\x^{2} +20x+99=0$

So, we need to find which option is equal to the expression we found.

However, neither of the choices are equivalent to the expression we found.

Therefore, the answer is none of the above.
