Find all real solutions and show work: <br> 2x^3-3x^2+18x-27=0
Amiraneli [1.4K]

Given:

The given equation is

2x^3-3x^2+18x-27=0

To find:

All the real solutions.

Solution:

We have,

2x^3-3x^2+18x-27=0

It can be written as

x^2(2x-3)+9(2x-3)=0

(2x-3)(x^2+9)=0

Using zero product property, we get

(2x-3)=0 and (x^2+9)=0

2x=3 and x^2=-9

x=\dfrac{3}{2} and x=\pm\sqrt{-9}

We know that x=\pm\sqrt{-9} is an imaginary number because there is a negative sign under the square root.

Therefore, x=\dfrac{3}{2} is the only real solution of the given equation.

Can someone plz help me solved this problem! I’m giving you 10 points! I need help plz help me! Will mark you as brainiest!
Kobotan [32]

Answer:  $2 or $9

<u>Step-by-step explanation:</u>

Revenue (R) = $1800 , x = 1100 - 100p

R = xp

1800 = (1100 - 100p)p             <em>substituted x with 1100 - 100p</em>

1800 = 1100p - 100p²             <em>distributed p into 1100 - 100p</em>

100p² - 1100p + 1800 = 0       <em>added 100p² & subtracted 1100p</em> on both sides

     p² - 11p + 18 = 0                <em>divided both sides by 100</em>

(p - 2) (p - 9) = 0                     <em>factored quadratic equation</em>

p = 2  p = 9                         <em>applied Zero Product Property to solve for p</em>
