Answer 3

Let's solve the equation step by step:

(2+x)³ - x²(6+x) = 11x + 19

Step 1: Expand the cube term (2+x)³

(2+x)³ = (2+x)(2+x)(2+x) = (4 + 4x + x²)(2+x) = 8 + 8x + 2x² + 2x + 2x³ + x² = 2x³ + 3x² + 10x + 8

Step 2: Expand the x²(6+x) term

x²(6+x) = 6x² + x³

Now our equation becomes:

2x³ + 3x² + 10x + 8 - (6x² + x³) = 11x + 19

Step 3: Combine like terms

2x³ - x³ + 3x² - 6x² + 10x - 11x + 8 = 19

x³ - 3x² - x + 8 = 19

Step 4: Move all terms to one side of the equation

x³ - 3x² - x + 8 - 19 = 0

x³ - 3x² - x - 11 = 0

The equation is now in standard cubic form (ax³ + bx² + cx + d = 0).
