FACTOR THE FOLLOWING, WITH SOLUTION 

1) X²+12x+20

3) X²+9x+18

4) X²-16x+15

5) X²-14x+24

6) X²-2x-24

7) X²+6x+16

Let's solve these quadratic expressions by factoring where possible.

### 1) \( x^2 + 12x + 20 \)

We need two numbers that multiply to 20 and add up to 12.  
These numbers are 10 and 2.  
So, the factorization is:

\[
x^2 + 12x + 20 = (x + 10)(x + 2)
\]

### 3) \( x^2 + 9x + 18 \)

We need two numbers that multiply to 18 and add up to 9.  
These numbers are 6 and 3.  
So, the factorization is:

\[
x^2 + 9x + 18 = (x + 6)(x + 3)
\]

### 4) \( x^2 - 16x + 15 \)

We need two numbers that multiply to 15 and add up to \(-16\).  
These numbers are \(-15\) and \(-1\).  
So, the factorization is:

\[
x^2 - 16x + 15 = (x - 15)(x - 1)
\]

### 5) \( x^2 - 14x + 24 \)

We need two numbers that multiply to 24 and add up to \(-14\).  
These numbers are \(-12\) and \(-2\).  
So, the factorization is:

\[
x^2 - 14x + 24 = (x - 12)(x - 2)
\]

### 6) \( x^2 - 2x - 24 \)

We need two numbers that multiply to \(-24\) and add up to \(-2\).  
These numbers are \(-6\) and 4.  
So, the factorization is:

\[
x^2 - 2x - 24 = (x - 6)(x + 4)
\]

### 7) \( x^2 + 6x + 16 \)

We need two numbers that multiply to 16 and add up to 6.  
However, there are no real numbers that satisfy this, so this expression **cannot be factored** using real numbers.  
It does not factor over the reals, but you could use the **quadratic formula** to find complex roots.
