What is the solution?. 1/2x2 – x + 5 = 0

AfilCa [17]

1/2 x^2 - x + 5 = 0
Multiply through by 2 to get:
x^2 - 2x + 10 = 0
$x= \frac{-b\pm\sqrt{b^2-4ac}}{2a}$ ; where a = 1, b = -2 and c = 10
$x=\frac{-(-2)\pm\sqrt{(-2)^2-(4\times1\times10)}}{2\times1}\\=\frac{2\pm\sqrt{4-40}}{2}\\=\frac{2\pm\sqrt{-36}}{2}\\=\frac{2\pm6i}{2}\\=1\pm3i$
Therefore, x = 1 + 3i or x = 1 - 3i

Help idk I don’t understand please ASAP

Pachacha [2.7K]

Answer:

x = 200/3

Step-by-step explanation:

Apply Thales theorem, we have:

80/(2x) = 60/27

Let's simplify both sides:

40/x = 20/9

x/40 = 9/20

Multiplying both sides by 40, we have:

(40/40)x = (20/9)*40

Let's simplify one more time:

x = (20*40)/(9)

x = 200/3

Hope this helps!
