Solve: (2x - 3)^2 = -4

Mathematics
1 answer:
Wewaii [24]3 years ago

Answer:

No real solutions;

x=i+1.5

Step-by-step explanation:

The easiest method to solve an algebraic equation is to use inverse operations. This applies to the given equation;

(2x-3)^2=-4\\

- Take the square root of both sides

\sqrt{}                

==================================================================

As one can see, the right side is a negative number. However, one cannot take the square root of a negative number and get a real result. Therefore, one must use imaginary numbers. Remember, the imaginary unit (i) represents (\sqrt{-1}).

==================================================================

2x-3=2i

- Add (3) to undo the (-3)

+3          

2x=2i+3

- Divide by (2) to remove the coefficient of (2x)

÷2           ÷

x=\frac{2i+3}{2}

Simplify,

x=i+1.5

find the equation of the straight line passing through the point (0,-1) which is perpendicular to the line y=-3/4x-3
barxatty [35]

Answer:

y = \frac{4}{3} x - 1

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

y = - \frac{3}{4} x - 3 is in this form

with slope m = - \frac{3}{4}

the slope of a perpendicular line is the negative reciprocal of m, hence

m_{perpendicular} = \frac{4}{3}

(0 , - 1 ) is the y-intercept ⇒ c = - 1

y = \frac{4}{3} x - 1  ← equation of perpendicular line
