Question

12х квадрате(х+9)=480

Answer 1

Ответ:

x=327

Пошаговое объяснение:

12х квадрате(х+9)=480

12*12=144

144x*(x+9)=480

480-9=471

144x:471

x=471-144

x=327

Answer 2

To solve the equation $12x^2(x+9) = 480$, follow these steps:

Step 1: Distribute the $12x^2$ term into the parentheses: $12x^2 \cdot x + 12x^2 \cdot 9 = 480$

Step 2: Simplify the equation: $12x^3 + 108x^2 = 480$

Step 3: Move all terms to one side of the equation to set it equal to zero: $12x^3 + 108x^2 - 480 = 0$

Step 4: Divide the entire equation by the greatest common divisor of the coefficients to simplify it further. In this case, the greatest common divisor is 12: $x^3 + 9x^2 - 40 = 0$

This is a cubic equation. Solving cubic equations can be more complex compared to quadratic equations, and there isn't a simple formula that works in all cases like the quadratic formula. You might need to use numerical methods or approximations to find the solutions. If you're looking for approximate solutions, you can use methods like graphing, factoring, or numerical root-finding algorithms.
