Answer 2

It looks like you have two quadratic equations that you want to solve. Let's work through each of them step by step.

1. Equation: 6x - 6x = 0

This equation simplifies to 0 = 0, which is always true. In this case, it means that the equation has infinitely many solutions because any value of x will satisfy it.

2. Equation: x² + 6x + 9 = 0

This is a quadratic equation, and we can solve it by factoring:

x² + 6x + 9 = 0

(x + 3)(x + 3) = 0

Now, we have a repeated factor of (x + 3). To solve for x, set each factor equal to zero:

x + 3 = 0

Now, subtract 3 from both sides:

x = -3

So, for this equation, the only solution is x = -3.

In summary, the first equation has infinitely many solutions, and the second equation has one solution, which is x = -3.
