Plz Help meee!!!<br><br>Factor the Trinomial<br><br>x^2+12x+27​
mojhsa [17]

Answer:

(x + 9)(x + 3)

Step-by-step explanation:

Factor 27 so that the factors, when combined, will equal 12:

x² + 12x + 27

x                9

x                3

(x + 9)(x + 3) is your answer.

Check: Use the FOIL method. Multiply the first two terms, the outside terms, the inside terms, and then the last two terms. Combine like terms:

(x + 9)(x + 3) = x² + 3x + 9x + 27 = x² + 12x + 27 (√)

Method One
Your calculator might be able to do this. Mine does it like this.
6
nCr
2  
= 
15

Method 2
You could simply set up 6C2

This gives you
\frac{n!}{(n- r)! r!} =  \frac{6!}{(6 - 2)!2!} =  \frac{6!}{4! 2!} =  \frac{6*5}{2*1} = 15

Method Three
You only have to do this a couple of times to see how the cancellation works.

\frac{6!}{4!2!} =  \frac{6*5*\st{4*3*2*1}}{4*3*2*1 * 2*1}
After all the cancellation takes place you have
6*5/2 = 15
