Answer:

f(x) = (x + 1)(x + 2)

Step-by-step explanation:

Given

f(x) = x² + 3x + 2

Consider the factors of the constant term (+ 2) which sum to give the coefficient of the x- term (+ 3)

The factors are + 1 and + 2, since

1 × 2 = 2 and 1 + 2 = 3, thus

f(x) = x² + 3x + 2 = (x + 1)(x + 2)

What is the standard deviation for 0,0,0,1,1,1,2,2,3,5?

Nadya [2.5K]

Standard Deviation, σ: 1.5
Count, N: 10
Sum, Σx: 15
Mean, μ: 1.5
Variance, σ2: 2.25

Steps

σ2 =
Σ(xi - μ)2
N
=
(0 - 1.5)2 + ... + (5 - 1.5)2
10
=
22.5
10
= 2.25
σ = √2.25
= 1.5

How do you simplify this?

timama [110]

Notice how the top is an addition of two cubes, namely x and 2.

You can rewrite the equation as:

$\frac{x^{3} + 2^{3}}{x + 2}$

Now, (a + b)³ can be simplified down to (a + b)(a² - ab + b²)
Following the same pattern, we get:

$\frac{(x + 2)(x^{2} - 2x + 4)}{x + 2}$
$= x^{2} - 2x + 4$
