What is x? 0=3x² - 4x + 12​

Mathematics
1 answer:
luda_lava [24]4 years ago
5 0

Answer:

x=0.66+1.88i

x=0.66-1.88i

Step-by-step explanation:

Given

3x^{2}-4x+12=0

using the Quadratic Formula where

a = 3, b = -4, and c = 12

x=-b±\sqrt{b^{2}-4ac } /2a\\

x=-(-4)±\sqrt{(-4)^{2}-4(3)(12) } /2(3)

x=4±\sqrt{16-144} /6

x=-4±\sqrt{128} /6

b^{2} -4ac

x=-4±8\sqrt{2} i/6

x=\frac{2}{3}± \frac{4\sqrt{2}i }{3}

Which becomes,

x=0.66+1.88i

x=0.66-1.88i

The value of x will be x=0.66+1.88i

x=0.66-1.88i

Hi answer for this please
miv72 [106K]

Answer:

x+79degree + 35degree = 180 degree ( being the sum of all angle of the triangle )

or, x + 114 degree = 180 degree

or, x = 180degree - 114degree

or, x = 66degree

hence, x = 66 degree.
