Answer 2

To solve the equation 11 - X²(X + 9) = 8X - (X + 3)³, follow these steps:

Step 1: Expand the expressions on both sides of the equation.

On the left side: 11 - X²(X + 9)

Expand X²(X + 9): 11 - (X³ + 9X²)

On the right side: 8X - (X + 3)³

Expand (X + 3)³: 8X - (X³ + 9X² + 27X + 27)

Step 2: Simplify the equation further.

Now that we've expanded both sides of the equation, the equation becomes:

11 - X³ - 9X² = 8X - X³ - 9X² - 27X - 27

Step 3: Rearrange and combine like terms.

Move all terms to one side of the equation:

11 - X³ - 9X² - 8X + X³ + 9X² + 27X + 27 = 0

Now, combine like terms:

11 - 8X + 27 = 0

Combine constants:

38 - 8X = 0

Step 4: Solve for X.

Subtract 38 from both sides of the equation:

-8X = -38

Now, divide both sides by -8 to isolate X:

X = -38 / -8

Simplify the right side:

X = 19/4

So, the solution to the equation is:

X = 19/4
