Find the solution using the Quadratic Formula. (show work) 2x + 8x+ 5 = 0 a. 47 ſ6 b. -27 56 c. -2± √3​
Nookie1986 [14]

Answer:

The roots of the equation for the given quadratic equation is               -2\pm \frac{\sqrt{6}}{2} .

Step-by-step explanation:

Given quadratic equation as :

2 x² + 8 x + 5 = 0

The roots of the quadratic equation  ax² + bx + c = 0 as can be find as :

x = \frac{-b\pm \sqrt{b^{2}-4\times a\times c}}{2\times a}

x = \frac{-8\pm \sqrt{8^{2}-4\times 2\times 5}}{2\times 2}

or, x = \frac{-8\pm \sqrt{64-40}}{4}

Or, x = \frac{-8\pm \sqrt{24}}{4}

Or, x = \frac{-8\pm 2\sqrt{6}}{4}

∴ x = -2\pm \frac{\sqrt{6}}{2}

Hence The roots of the equation for the given quadratic equation is -2\pm \frac{\sqrt{6}}{2} . Answer

Alina [70]
2x² - 128

2(x² - 64), but (x² - 64)  = x² - 8² (difference of 2 squares),[a²-b²=(a-b)(a+b)]

2(x² - 64) = 2(x² - 8²) = 2(x-8)(x+8)

Given a medicine provides 3.6 milligrams of medicine. Therefore, the amount of medicine the dog will have in a week is,

The amount of medicine = 3.6milligrams × 7 = 25.2 milligrams

Hence, the amount of medicine that Lamar's dog will have in one week is 25.2 milligrams.
