Find all real solutions and show work: 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.

Answer: $2 or $9

Step-by-step explanation:

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

R = xp

1800 = (1100 - 100p)p substituted x with 1100 - 100p

1800 = 1100p - 100p² distributed p into 1100 - 100p

100p² - 1100p + 1800 = 0 added 100p² & subtracted 1100p on both sides

p² - 11p + 18 = 0 divided both sides by 100

(p - 2) (p - 9) = 0 factored quadratic equation

p = 2 p = 9 applied Zero Product Property to solve for p
