Please someone help me, I will give you brainliest <br><br> Factor the expression: y^2 + y + 1/4
Firdavs [7]

Answer:

y² + y + \frac{1}{4} = (y + \frac{1}{2})²

Step-by-step explanation:

In most cases, we can factor a polynomial, or quadratic, by looking at the factors of the last term.  In this case, the last term is \frac{1}{4}.  When we factor a polynomial, we are looking for two expressions that when multiplied together using FOIL (forward-outside-inside-last) will give us the polynomial.  For example: (a + b)(a + b) or (a+ b)².

In order to get y² + y + \frac{1}{4}, we are looking for a 'c' value that will add up to '1' which is our 'b' value (ay² + by + c).

Since \frac{1}{2}*\frac{1}{2}=\frac{1}{4}and\frac{1}{2}+\frac{1}{2}=1

Then, we can use \frac{1}{2} as our factor for both expressions.  Putting this together we get:  (y + \frac{1}{2})(y + \frac{1}{2}) or (y + \frac{1}{2})²

2/3 of the baked chicken was left over. Michela ate 1/4 of the leftover chicken. How much of the whole chicken did Michela eat?
geniusboy [140]
Greetings!

"<span>2/3 of the baked chicken was left over. Michela ate 1/4 of the leftover chicken. How much of the whole chicken did Michela eat?"...

This can solved by multiplying the fraction by each other:

2/3*1/4
2*1=2
3*4=12
=2/12 or 1/6.

She 1/6 of the whole chicken.

Hope this helps.
