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

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
