what do you need help with?
Here, we are having a quadratic equation in one variable because the highest degree is 2 and contains only one variable i.e. x
Given, equation:
Now, if we observe the terms used in the polynomial, 81x² and 100 separated by a negative sign, we can analyze and can factorise using the identity:
Consider:
So, let's factorise by using the above identity
Here, a = 9x and b = 10,
Is the factorised form of 81x² - 100
So Correct Option is: Option C

We can conclude that Donald is the shortest friend.
<h3>
Who is the shortest?</h3>
This is a logical question, first, we know that the tallest friend will be on the left side, so we assume that the left position can be discarded, so we need to find who is in the right position.
Barry is not in the center and is not the youngest, so Barry is the tallest friend.
Donald is not in the center, and we know that the youngest must be on the right of Adam. So the only position left for Donald is the right one.
Then, we can conclude that Adam must be on the center and Donald on the right extreme. Then Donald is the youngest and shortest friend.
