Answer 2

Solving the equation (-3x)2u + 3 = 0

Let's break this down step-by-step: 1. (-3x)2 = 9x2 2. u + 3 = 0 3. 9x2u + 27x2 = 0

The key steps are: - Squaring the expression (-3x) gives us 9x2 - Isolating the u term and setting it equal to -3 - Distributing the 9x2 to get the fully expanded equation

To solve this, we factorize the left side: (3x)2(3u - 9) = 0

Then, using the zero product property: 3x = 0 or 3u - 9 = 0

Solving each branch gives: x = 0 u = 3

So the solutions are: x = 0, u = 3
