Question

-2xx+3x-4=0 what is the answer? Its -2x square.

Answer 1

Answer:

complex numbers

x = (3 - √23i) / 4          ,       x =  (3 + √23i) / 4

Step-by-step explanation:

Given in the question that polynomial equation is

-2x² + 3x - 4 = 0

It is a quadratic equation which can be solve by using quadratic formula

x = −b ± √(b² − 4ac) / 2a

where a = -2

           b = 3

​     c = -4

x = -(3) ± √(-3)² - 4(-2)(-4) / 2(-2)

x = -3 ± √9 - 4(8) /2(-2)

x = -3 ± √9 -32 / -4

x = (-3 + √9 -32) / -4             ,       x = (-3 - √9 -32) / -4

x = (-3 + √-23) / -4                ,       x = (-3 - √-23) / -4

x = (-3 + √23i) / -4                ,       x =  (-3 - √23i) / -4

x = (3 - √23i) / 4                   ,       x =  (3 + √23i) / 4
