Answer:
'n plus 5 squared' is n + 25
Step-by-step explanation:
Note that "five squared" is 5^2, or 25.
Then 'n plus 5 squared' is n + 25.
Given: y²+5y
Converting y²+5y in the form: x²+2ax+a²
Here 2a=5 or a=5/2
Add and subtract (5/2)²
y²+5y+(5/2)²-(5/2)²
Complete the square.
(y+5/2)²-(5/2)²
Simplify
(y+5/2)² - 25/4
Answer: (y+5/2)² - 25/4

Answer:
B. -3 1/2y + 2
Step-by-step explanation:
Our expression is:
.
Let's first distribute out that parentheses. Remember that distribution is simply taking the sum of the product of the outside term with each of the inside terms. Here, the outside term is 1/2 and the inside terms are 4 and -2y:

Now, we have:

We want to combine like terms, which means combining all the terms with y in them:

Remember that -7/2 can be written as the mixed number -3 1/2, so our final answer is:
-3 1/2y + 2
The answer is thus B.
