Answer 1

The given equation is \(x^2 + 4x + 3 = 0\).

To complete the statements:

1. The value of \(a\) is **1** (coefficient of \(x^2\)).
2. The value of \(b\) is **4** (coefficient of \(x\)).
3. The value of \(c\) is **3** (constant term).

To find one solution to the equation, we can factor it:

The equation can be factored as \((x + 1)(x + 3) = 0\).

Setting each factor equal to zero gives:

1. \(x + 1 = 0 \rightarrow x = -1\)
2. \(x + 3 = 0 \rightarrow x = -3\)

Therefore, one solution to the equation is **-1** (you could also state -3 as another solution, but since only one is requested, we give -1).

So, the completed statements are:

- The value of \(a\) is **1**.
- The value of \(b\) is **4**.
- The value of \(c\) is **3**.
- One solution to the equation is **-1**.
