Answer:48
Step-by-step explanation:
Answer:
This number is 5008405
Step-by-step explanation:
five million = 5000000
eight thousand = 8000
four hundred = 400
five = 5
Answer:
8x + 2
Step-by-step explanation:
Like terms:
6x and 2x
-3 and 5
6x + 2x = 8x
5 - 3 = 2
8x + 2
Two times the variable x plus eight is greater than but not equal to negative four.
By applying the <em>quadratic</em> formula we conclude that the roots of the <em>quadratic</em> equation y = 2 · x² - 4 · x - 3 are 1 + 0.5√10 and 1 - 0.5√10, respectively.
<h3>How to find the roots of a quadratic equation </h3>
All <em>quadratic</em> equations of the form a · x² + b · x + c = 0 have two roots that can be found by using the <em>quadratic</em> formula:
(1)
If we know that a = 2, b = - 4 and c = - 3, then the roots of the <em>quadratic</em> equations are:
![x = \frac{4 \pm \sqrt{(-4)^{2}-4\cdot (2) \cdot (- 3)}}{2\cdot (2)}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B4%20%5Cpm%20%5Csqrt%7B%28-4%29%5E%7B2%7D-4%5Ccdot%20%282%29%20%5Ccdot%20%28-%203%29%7D%7D%7B2%5Ccdot%20%282%29%7D)
![x = 1 \pm \frac{\sqrt{40}}{4}](https://tex.z-dn.net/?f=x%20%3D%201%20%5Cpm%20%5Cfrac%7B%5Csqrt%7B40%7D%7D%7B4%7D)
![x = 1 \pm \frac{\sqrt{10}}{2}](https://tex.z-dn.net/?f=x%20%3D%201%20%5Cpm%20%5Cfrac%7B%5Csqrt%7B10%7D%7D%7B2%7D)
By applying the <em>quadratic</em> formula we conclude that the roots of the <em>quadratic</em> equation y = 2 · x² - 4 · x - 3 are 1 + 0.5√10 and 1 - 0.5√10, respectively.
