Among all these no., see the first no. that lies before or left side of decimal point, here... 2 is common so next check the no. After decimal... 2.0, 2.2, 2.4, 2 is considered as 2.0 and then we have 2.0... Let's not take 2.0s and let's take 2.2 and 2.4 which is greater than 2.0. Next see the second no. That comes after decimal We have 2.24 and 2.4 which can be taken as 2.40... The no.s after decimal, 24 is greater than 40 so 2.4 is greater...

Find the difference of <br> (3c-d)^2

OverLord2011 [107]

Answer:

<u>9c² - 6cd + d²</u>

Explanation:

To find the difference (3c - d)² you should recognize that it is the square of a difference of two terms.

The square of the difference of two terms is a special case that you should remember: it is equal to the square of the first, minus twice the product of the first and second, plus the square of the second:

(x - y)² = x² - 2xy + y²

For the binomial (3c - d)² you have that:

x = 3c

y = d

Thus:

(3c -d)² = (3c)² - 2(3c)(d) + d² = 9c² -6cd + d² ← answer
