Answer 2

Solution to the Equation (x-4)(x+2)(x+8)(x+14) = 354

To solve the equation (x-4)(x+2)(x+8)(x+14) = 354 without using exponents or substitution, we can use the method of factoring.

Let's break down the steps to solve this equation:

1. Expand the equation: (x-4)(x+2)(x+8)(x+14) = 354

By expanding the equation, we get: x^4 + 20x^3 + 132x^2 + 288x - 448 = 354

2. Rearrange the equation: x^4 + 20x^3 + 132x^2 + 288x - 802 = 0

3. Now, we need to find the roots of this equation. Unfortunately, there is no simple algebraic method to find the roots of a quartic equation (equation with a degree of 4) without using exponents or substitution. In this case, we can use numerical methods or calculators to find the approximate solutions.

Using a numerical method or calculator, we find that the approximate solutions to the equation are: x ≈ -15.39, x ≈ -8.32, x ≈ 0.36, and x ≈ 7.35.

Please note that these are approximate solutions and may not be exact.

Therefore, the solutions to the equation (x-4)(x+2)(x+8)(x+14) = 354 without using exponents or substitution are approximately x ≈ -15.39, x ≈ -8.32, x ≈ 0.36, and x ≈ 7.35.
