The factors of the given quadratic expression, 2x² - 4x - 16, are 2, (x +2), and (x -4)

<h3>Factoring a Quadratic expression </h3>

From the question, we are to determine the each of the factors of the given quadratic expression

The given quadratic expression is

2x² - 4x - 16

Factoring

2x² - 4x - 16

First, factor out 2

That is,

2(x² - 2x - 8)

Now, we will factor x² - 2x - 8
x² - 2x - 8

x² - 4x + 2x - 8

x(x - 4) +2(x -4)

(x +2)(x -4)

Thus,

2x² - 4x - 16  = 2(x +2)(x -4)

Hence, the factors of the given quadratic expression, 2x² - 4x - 16, are 2, (x +2), and (x -4)

At Maddison high school each student studies one foreign language is 3/5 take Spanish and one-fourth of the remaining take germa
Snezhnost [94]

Answer:

Step-by-step explanation:

3/5 = 0.6

1 - 0.6 = 0.4 students left

Multiply the amount of students remaining by the fractional amount that take German

0.4  x  1/4   =   0.1

1 - 0.6 - 0.1 = 0.3

0.3 x 100 = 30%

Therefore 30% of students take French

Colt1911 [192]

Answer:

\huge \boxed{ \boxed{(a  -  {b)}^{2} } }

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about:</h3>
  • algebra
<h3>tips and formulas:</h3>
  • algebraic identity:(a-b)²=(a+b)²-4ab
<h3>let's solve:</h3>

therefore

using the identity our answer is (a-b)²

let's prove it

  1. (a-b)²:a²-2ab+b²
  2. rewrite -2ab as 2ab-4ab:a²+b²+2ab-4ab
  3. use (a+b)²=a²+2ab+c²:(a+b)²-4ab

therefore

we have also proven that
