Answer :

Sure, let's solve these equations by factoring step by step!

### 1. Solve [tex]\(x^2 - 9 = 0\)[/tex] by factoring:

1. Notice that [tex]\(x^2 - 9\)[/tex] is a difference of squares. The formula for difference of squares is:
[tex]\[ a^2 - b^2 = (a - b)(a + b) \][/tex]

2. Here, [tex]\(a = x\)[/tex] and [tex]\(b = 3\)[/tex]. So:
[tex]\[ x^2 - 9 = x^2 - 3^2 = (x - 3)(x + 3) \][/tex]

3. Set each factor equal to 0:
[tex]\[ (x - 3)(x + 3) = 0 \][/tex]

4. Solve for [tex]\(x\)[/tex]:
[tex]\[ x - 3 = 0 \quad \text{or} \quad x + 3 = 0 \][/tex]
[tex]\[ x = 3 \quad \text{or} \quad x = -3 \][/tex]

So the solutions to [tex]\(x^2 - 9 = 0\)[/tex] are:
[tex]\[ x = 3, \quad x = -3 \][/tex]

### 2. Solve [tex]\(2x^2 + 37x + 36 = 0\)[/tex] by factoring:

1. We need to factor the quadratic expression [tex]\(2x^2 + 37x + 36\)[/tex]. We look for two numbers that multiply to [tex]\(2 \times 36 = 72\)[/tex] and add up to [tex]\(37\)[/tex].

2. The numbers [tex]\(1\)[/tex] and [tex]\(72\)[/tex] satisfy this requirement because:
\[
1 \times 72 = 72 \quad \text{and} \quad 1 + 72 = 73 \quad \rightarrow \text{These numbers do not sum up to 37}
y

3. Retry with different pairs: [tex]\(2\)[/tex] and [tex]\(36\)[/tex]

4. Similarly checking further pairs, we notice that [tex]\(39\)[/tex] is not between factors of [tex]\(72\)[/tex]. Further pairs will also not match as no pairs have [tex]\(37\)[/tex].

So the numbers \(we can write further break down as per availability:
