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

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

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

for the first question it would be the second answer for the second question it would be the third answer and for the third question it would be the first answer

step-by-step explanation:

y -5 = (-1/4)(x + 8)
